SolidWorks CAD Assistant & MCP Server

Languages: English | Español

Python 3.13+ License: MIT Windows SolidWorks Coverage

Python MCP server for SolidWorks automation with 156 tools, plus an optional agent/prompt-testing layer for AI-assisted workflows.

155 MCP tools by support level, and how much of the core SolidWorks COM API they reach

Generated from the code; click it for every tool, its level and why, filterable by level and family.

Two tools in one

  • A Python interface for scripting SolidWorks. The adapters wrap SolidWorks' COM API in plain async Python calls, so you can automate it from your own scripts without an AI in the loop:

    from solidworks_mcp.adapters.base import ExtrusionParameters
    from solidworks_mcp.adapters.pywin32_adapter import PyWin32Adapter
    
    adapter = PyWin32Adapter({})
    await adapter.connect()
    await adapter.create_part()
    await adapter.create_sketch("Top")
    await adapter.add_rectangle(-20, -10, 20, 10)  # mm
    await adapter.exit_sketch()
    await adapter.create_extrusion(ExtrusionParameters(depth=10))
  • An MCP tool server on top of it. The same calls, exposed as 156 MCP tools, so an agent such as Claude Code can build parts, assemblies and drawings from a description. Each tool carries a support level (stable, beta, experimental or planned), so the agent knows how far to trust it.

A whole mechanism from a description

I took SolidWorks' own U-Joint sample, read every part, sketch, feature and mate, and wrote it up as a plain-English prompt: eight parts, a crank sub-assembly, and a main assembly that has to move like a real joint. Then Claude Code (Opus 5.5, medium effort) built it from that prompt alone.

I want to build a small hand-cranked universal joint in SolidWorks: eight parts, a crank sub-assembly, and the main assembly. It's a mechanism: turning the knob turns the crank, which drives the joint through an angle, so the assemblies must still move the way described in sections 9 and 10. Please reason through each part before you start drawing, check every part once it's built, and tell me if something can't be done with the tools rather than guessing. All sizes are in millimetres (the original was drawn in inches, so the numbers are odd). SolidWorks' Y axis is up. Save every part and both assemblies in this folder, with the names given below.

1. bracket.SLDPRT: a bent plate, 6.35 mm thick and 38.1 mm wide. Seen from the side (sketch on the Right plane, Y up, Z towards the front), the inside outline of the bend is an open chain:

  • a back wall going straight up 82.55 mm from the origin;

  • from its top, a top arm going forward 57.15 mm;

  • from the origin, a bottom foot going forward 44.45 mm;

  • from the front of the foot, a lip rising at 40° for 42.77 mm (it ends 27.49 mm up and 77.22 mm forward). The 6.35 mm thickness is on the outside of that outline: above the top arm, behind the back wall and under the foot. The 38.1 mm width is centred on the Right plane. Drill a 12.7 mm hole straight down through the top arm and on through the foot below it (one cut, both plates), centred across the width and 38.1 mm forward of the back wall's inside face.

2. Yoke_male.SLDPRT: a fork with a stub shaft.

  • Start with a 38.1 mm diameter cylinder, 47.625 mm tall, standing on the Top plane.

  • Its bottom becomes a fork with two ears. Each ear is 19.05 mm wide and 8.89 mm thick, and the gap between them is 20.32 mm, centred. Each ear has a rounded end: a full radius of 9.525 mm, centred 9.525 mm above the bottom. Where an ear meets the solid part of the cylinder, round the shoulder with a 9.525 mm radius, so the solid part starts 29.21 mm above the bottom.

  • Drill a 9.525 mm cross hole through both ears at the centre of their rounded ends, square to the ears.

  • On top, add a 12.7 mm diameter stub, 19.05 mm tall, on the cylinder's axis. Chamfer its top edge 1.27 mm at 60°.

  • Cut a flat on the stub, 12.7 mm long down from its top. The flat is 4.7625 mm from the axis, so it is 1.5875 mm deep.

3. Yoke_female.SLDPRT: the same 38.1 x 47.625 mm cylinder with the same fork and the same cross hole as the male yoke, but no stub. Instead, a 9.525 mm hole goes all the way through along its axis.

4. spider.SLDPRT: a 19.05 mm cube centred on the origin. It has two 9.525 mm holes, both through its centre: one front to back, and one left to right.

5. pin.SLDPRT: a 9.398 mm diameter rod, 38.1 mm long.

6. crank-shaft.SLDPRT: a 12.573 mm diameter shaft, 40 mm long, standing on the Top plane.

  • Around its bottom 15.875 mm, a collar 18.923 mm in diameter.

  • A 4.763 mm fillet where the collar meets the shaft, and a 4.763 mm fillet on the collar's top outer edge.

  • In the bottom, a D-shaped socket 12.7 mm deep. It is a 12.954 mm circle with a flat 4.889 mm from the axis, to take the male yoke's stub.

  • A 2.381 mm cross hole through the collar wall, square to the socket's flat and 6.35 mm up from the bottom.

  • At the top, a matching flat 6.35 mm long, 4.889 mm from the axis.

  • A 0.794 mm x 45° chamfer on the top end.

7. crank-arm.SLDPRT: a flat bar, 75 x 19.05 x 6.35 mm.

  • Near one end, a 12.7 mm D-hole centred 9.525 mm from the end and on the bar's centreline. Its flat is 4.889 mm from the hole's centre, towards that end. It fits the shaft's top flat.

  • Near the other end, a 4.763 mm hole 9.525 mm from that end, also on the centreline.

8. crank-knob.SLDPRT: a mushroom-shaped knob, revolved 360° about the vertical axis. Going up from the bottom, its profile has:

  • a 4.572 mm diameter shank, 6.35 mm long;

  • a step out to a 9.525 mm diameter;

  • a concave quarter-round of radius 6.35 mm that flares out to 22.225 mm diameter, 12.7 mm up;

  • a convex half-round of radius 4.7625 mm that reaches 31.75 mm diameter at its widest;

  • a flat top 22.225 mm in diameter, 22.225 mm above the bottom.

9. crank sub.SLDASM:

  • The crank shaft is fixed.

  • The crank arm's D-hole goes on the shaft's top flat: the hole is concentric with the shaft, the flats are parallel, and the arm sits on the shoulder where the flat starts. The flats lock the arm to the shaft, so they turn together.

  • The knob's shank goes into the arm's small hole, with the knob's step resting on the arm's top face. The knob stays free to spin in its hole, like a handle.

10. UJoint.SLDASM:

  • The bracket is fixed.

  • The male yoke hangs under the bracket's top arm. Its stub goes up through the bracket's hole (concentric), and the top of its cylinder is flat against the underside of the arm. It must stay free to turn in that hole.

  • The spider sits centred between the male yoke's ears, with one of its holes lined up with the ears' cross hole. It pivots on that axis.

  • The female yoke's ears go around the spider's other hole, centred on the spider. Its top face is parallel to the bracket's sloped lip, so its axis points down and forward. It pivots on the spider and turns about its own axis.

  • Put one pin through the male yoke's ears and the spider, and one pin through the female yoke's ears and the spider. Each pin's ends are flush with its yoke's round outside, and each pin turns with its yoke.

  • Insert the crank sub-assembly. Its shaft's D-socket goes over the male yoke's stub: concentric, with the flats parallel, and the bottom of the shaft 1 mm above the top of the bracket. The flats lock the crank to the male yoke.

  • The result should be a mechanism with one free motion: turning the knob around the crank shaft's axis turns the male yoke, the spider rocks on its pins, and the female yoke turns about its tilted axis. Choose mates that leave exactly those rotations free and lock everything else.

When it's all built, check each part's size and the assembly's component and mate counts, say which rotations your mates leave free, and tell me what you couldn't do.

The original U-Joint sample beside the agent's build: the same bracket, yokes, spider, pins, crank and knob, in the same pose

The agent's 294 tool calls replayed in SolidWorks: eight parts sketched and cut, then the crank sub-assembly and the U-joint mated together

Six of the eight parts match the sample's volume within 0.2 %, and all eight within 1 %. The mates leave the mechanism free to turn. The recording replays the session's 294 calls (sped up 80 times). The walkthrough has the prompt, the part-by-part comparison, and what the agent couldn't do. The same prompt run with and without the agent skill made the same parts, which is why I want skills that improve results (#207).

A drawing package from one prompt

Make a 100 x 50 x 10 mm AISI 1020 mounting plate with four M5 clearance holes, 10 mm in from each edge, and draw it fully dimensioned. Stack two of them 10 mm apart, check the result, and draw the assembly with a BOM.

A fully dimensioned plate, its drawing with GD&T, two plates mated 10 mm apart and the assembly drawing with a BOM, built in SolidWorks through the MCP tools

The 58 tool calls an agent made from that prompt, run against SolidWorks 2026 through the same MCP tools a client calls, and recorded (sped up five times). Each result is checked against a hand calculation: the plate's volume and mass, the 10 mm gap and the BOM quantity. This is a replay of the calls, not a recorded model session.

Note: the demo is not perfect, and is not the most efficient way to get this result. The run pauses after each call so it can be read, and the calls are chosen to show what the tools can do: every sketch dimension is added one at a time, and the mate distance is stepped down only so the plates are seen coming together.

The walkthrough in the docs has the agent's plan and every call with its arguments. Run it yourself with the README demo; the calls are also in plate_stack_calls.json.

  1. Sketch (24 calls): create_sketch on Top; four add_line for the 100 x 50 outline; add_circle for each Ø5.5 hole; add_sketch_dimension for the 100, the 50, one Ø5.5 and each hole 10 mm from two edges; add_sketch_constraint making the other three holes equal; exit_sketch

  2. Check and extrude: check_sketch_fully_defined, create_extrusion 10 mm (+49 049.7 mm³ read back)

  3. Material and check: list_model_dimensions (finds the Ø5.5 by value), set_material AISI 1020, verify_model (volume, mass 0.3875 kg, size, 1 feature, 1 body)

  4. Plate drawing: generate_drawing_package PS-01 (A3, four views, every model dimension laid out with no overlaps, notes, title block, PDF), auto_center_marks

  5. GD&T: add_datum_tag A, B and C, then add_gtol ⊕ Ø0.2 Ⓜ A|B|C on the Ø5.5

  6. Assembly: insert_component twice, list_components, add_mate Front and Right coincident and Top planes 60 mm apart, set_dimension stepping that distance down to 20 mm (10 calls), verify_model (2 parts, 3 mates, no interference; the stack measures 30 mm, so the gap is 10 mm)

  7. Assembly drawing: set_custom_property Material, generate_drawing_package PS-02 with include_bom (the BOM above the isometric: Demo Plate, QTY 2), then the same datums and position frame

  3. execute MCP tools

  4. inspect results

  5. iterate

It includes:

  • core MCP runtime for SolidWorks tool execution

  • COM/VBA routing and adapter safety wrappers

  • tool coverage across modeling, sketching, drawing, analysis, export, automation, templates, and macros

  • optional agent orchestration/testing utilities under src/solidworks_mcp/agents/

Demos

Each GIF is a live test driving SolidWorks 2026 through the MCP tools, with the call and its result captioned beneath. Click one to see what it checks, a prompt that asks for it, and its tool calls.

See every demo in the docs: what each one shows, its prompt, every tool call with its arguments (all 58 for the demo at the top), and how to run them yourself.

Supported Today

  • Windows + SolidWorks COM automation for the main CAD lifecycle.

  • Tested on SolidWorks 2026. Earlier versions may work but are untested. To check yours, run uvx solidworks-mcp-python selftest with SolidWorks open, then send the result with the compatibility report form. The compatibility page lists the releases checked so far.

  • Modeling, sketching, drawing, analysis, export, automation, templates, and macro tools.

  • Every tool's support level, and the reason a tool isn't stable yet, is on the progress page.

Not Yet / Simulated

  • Mock adapter output is simulated and should not be treated as engineering truth.

  • Live 3D viewport streaming in a UI.

  • Checkpoint-level interference validation.

  • Simple simulation and fluid workflows

  • Simple Topology Optimization via SimulationXpress etc.

Install

You need Windows 10 or 11 and SolidWorks (opened at least once). In PowerShell, install uv, then open a new PowerShell window and run setup:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
uvx solidworks-mcp-python setup

uv fetches Python 3.13 and the server from PyPI by itself; nothing to clone. The guided setup then:

  1. finds your SolidWorks version and the MCP clients on your PC: Claude Desktop, Claude Code, VS Code, Cursor and LM Studio;

  2. lets you pick which clients to connect;

  3. starts the server once to check that it lists its tools (in mock mode, so SolidWorks isn't touched);

  4. adds a solidworks entry to each client you picked, then tells you what to restart.

Nothing needs a login or an API key, and the server runs only on your PC. Setup changes only the solidworks entry in each client's config. It backs the file up first and never shows or changes your other servers. Other entries that start this server the old way (run-mcp.ps1 and the like) are offered for removal, so tools don't load twice.

To check it worked: open SolidWorks, restart your client, and ask "What model is open in SolidWorks?"

The package is solidworks-mcp-python. uvx solidworks-mcp installs a different project. To work on the server itself, install from a clone. More fixes are in Troubleshooting.

Connect your client

Run setup again whenever you want to add a client:

uvx solidworks-mcp-python setup

Option

What it does

--client claude-desktop

Configure one client without the list. Repeat it for several (claude-code, vscode, cursor, lmstudio).

--dry-run

Show what would change, and change nothing.

--yes

Don't ask: configure every client found.

--remove

Take the solidworks entry out again.

--replace-old

Remove older entries for this server without asking.

--mock

Configure mock mode, which answers without SolidWorks (for trying the tools).

--year 2026

The SolidWorks release to start the server with. Default: the newest installed.

To set up a client by hand instead, each one runs uvx solidworks-mcp-python --year 2026, with your SolidWorks year. --year names your installed SolidWorks release and is required for real SolidWorks; setup fills it in for you. It picks which SolidWorks API the lookup tools answer for. Without it, the server logs a warning and uses the newest installed release. If a client can't find uvx, use its full path, from (Get-Command uvx).Source.

Add this to claude_desktop_config.json, alongside anything already in it. Depending on how Claude Desktop was installed, the file is in one of:

  • %LOCALAPPDATA%\Claude-Data\claude_<id>\ (current releases)

  • %LOCALAPPDATA%\Packages\Claude_<id>\LocalCache\Roaming\Claude\

  • %APPDATA%\Claude\

{
  "mcpServers": {
    "solidworks": {
      "command": "uvx",
      "args": ["solidworks-mcp-python", "--year", "2026"]
    }
  }
}

Quit Claude Desktop from the system tray (closing the window isn't enough) and reopen it. Settings > Developer should show solidworks as running.

claude mcp add --scope user solidworks -- uvx solidworks-mcp-python --year 2026

Run /mcp in a new session to check that solidworks is connected.

Add this to %APPDATA%\Code\User\mcp.json:

{
  "servers": {
    "solidworks": {
      "type": "stdio",
      "command": "uvx",
      "args": ["solidworks-mcp-python", "--year", "2026"]
    }
  }
}

Run MCP: List Servers from the Command Palette and start solidworks. Its output should end with Discovered 156 tools (the count grows as tools are added).

Add this to %USERPROFILE%\.lmstudio\mcp.json:

{
  "mcpServers": {
    "solidworks": {
      "command": "uvx",
      "args": ["solidworks-mcp-python", "--year", "2026"]
    }
  }
}

Restart LM Studio and enable solidworks in the Program tab.

For mock mode, which needs no SolidWorks, use "args": ["solidworks-mcp-python", "--mock"]. Linux and WSL work for the docs, the tests and mock mode, but not for driving SolidWorks.

Set these in your client's env block for the server, or in the shell before starting it by hand. Every SOLIDWORKS_MCP_<FIELD> maps to the config field of the same name.

SolidWorks-as-Code session logging (off by default). Logs every adapter tool call to a local SQLite database, so a session can be replayed or exported as a runnable Python script (see docs/getting-started/solidworks-as-code.md).

Variable

Default

Meaning

SOLIDWORKS_MCP_SOC_LOGGING_ENABLED

false

Turn logging on.

SOLIDWORKS_MCP_SOC_SESSION_ID

(generated)

Session name to log under. If unset while logging is on, a soc-YYYYMMDD-HHMMSS id is generated at startup.

SOLIDWORKS_MCP_SOC_DB_PATH

.solidworks_mcp/agent_memory.sqlite3

Override the database file.

$env:SOLIDWORKS_MCP_SOC_LOGGING_ENABLED = "true"
$env:SOLIDWORKS_MCP_SOC_SESSION_ID = "my-bracket"
.\.venv\Scripts\solidworks-mcp.exe
# ...work in your MCP client...
.\.venv\Scripts\python.exe -m solidworks_mcp.agents.soc_exporter my-bracket my_bracket.py

It works only with the circuit-breaker adapter wrapper (the default for real SolidWorks); the mock adapter does not log.

API docs index auto-refresh (on by default). The API-lookup tools (lookup_api_interface, lookup_api_method, find_related_api_members) and search_solidworks_api_help read a JSON index built by discover_solidworks_docs. When the index is older than the threshold, the next lookup rebuilds it.

Variable

Default

Meaning

SOLIDWORKS_MCP_DOCS_INDEX_AUTO_REFRESH

true

Rebuild a stale index automatically. No-op without SolidWorks + win32com; a failed rebuild keeps serving the existing index.

SOLIDWORKS_MCP_DOCS_INDEX_MAX_AGE_DAYS

21

Age after which the index counts as stale.

Teach your agent the workflow

Each tool's description says what that tool does. The solidworks-mcp skill covers what spans tools: the order to build in (sketch, close it, then the feature), which inputs take millimetres and which take metres, how to pick faces and edges, checking the result with verify_model, recovering from errors, and the tools that don't work yet. Install it into Claude Code with:

uvx solidworks-mcp-python skill install

That writes ~/.claude/skills/solidworks-mcp/. Add --project for the current project's .claude/skills, or --dir <folder> for another agent's skills folder. It writes only that folder and needs no login. Re-run it after an upgrade.

Clients that read MCP resources don't need the install: the server serves the same skill at skill://solidworks-mcp/SKILL.md, and points to it in the instructions it sends when a client connects. More: Agent skill.

Contributing

install.ps1 gives you an editable install, so code changes take effect the next time a client starts the server. For the development tools, install the extras:

.\.venv\Scripts\python.exe -m pip install -e ".[dev,test,docs]"

.\dev-commands.ps1 lists the common workflows:

  • dev-install: install or update the local dev environment

  • dev-test: run the standard test suite (the CI-safe subset)

  • dev-test-full: run the full suite, including smoke and integration paths

  • dev-lint and dev-format: lint checks and formatting

  • dev-docs-build, dev-docs-strict and dev-docs-audit: build the docs, build them failing on warnings, or write an audit report to .generated/docs

To mirror GitHub Actions CI locally (Ubuntu, the conda env from solidworks_mcp.yml, and make test), run .\scripts\run-ci-local.ps1. The first run builds the image; add -NoBuild to re-run tests without rebuilding.

Inputs: input_data (required). Returns: object

add_centerlineA

Add a centerline to the current sketch.

Creates a construction/reference line that serves as a centerline for symmetrical features, revolution axes, or construction geometry. Centerlines are non-geometric entities used for reference only.

Inputs: input_data (required). Returns: object

add_chamferB

Add an equal-distance chamfer to selected edges of the current model.

Chamfers the specified named edges with the given distance. Edge names use the SolidWorks convention, e.g. 'Edge<1>', or you can leave edge_names empty to chamfer all edges if the adapter supports it.

Inputs: input_data (required). Returns: object

add_circleB

Add a circle to the current sketch.

Inputs: input_data (required). Returns: object

Supports configuring the target drawing, view type, parent view, scale, and placement coordinates for common drawing view workflows.

Inputs: input_data (required). Returns: object

add_ellipseA

Add an ellipse to the current sketch.

Creates an elliptical entity with specified center and major/minor axes. Ellipses are useful for creating oval holes, ergonomic profiles, and complex curved features in mechanical and industrial design.

Inputs: input_data (required). Returns: object

add_filletA

Add a fillet (rounded edge) to selected edges of the current model.

Rounds the specified named edges with the given radius. Edge names use the SolidWorks convention, e.g. 'Edge<1>', or you can leave edge_names empty to fillet all edges if the adapter supports it.

Inputs: input_data (required). Returns: object

add_gtolC

Add a GD&T feature control frame, e.g. position Ø0.2 (M) to A|B|C.

Inputs: input_data. Returns: object

add_lineC

Adds a line segment between two points in the active sketch. Lines are fundamental sketch entities used for creating profiles, construction geometry, and complex shapes.

Inputs: input_data (required). Returns: object

add_mateA

Mate two components in the active assembly.

Positions components relative to one another — coincident planes to stack or align them, concentric to line up axes, distance to hold a gap.

Entities are selected by feature name, so only each component's reference planes and axes can be mated. Mating to a specific face or edge needs entity names this adapter cannot enumerate.

Inputs: input_data (required). Returns: object

add_noteC

Add a note or annotation to the current drawing.

Creates text annotations, callouts, and notes on drawings for specifications, instructions, and additional manufacturing information. Essential for comprehensive technical documentation.

Inputs: input_data (required). Returns: object

add_polygonB

Inputs: input_data (required). Returns: object

add_rectangleB

Add a rectangle to the current sketch.

Creates a rectangular profile defined by two opposite corner points, automatically generating four connected line segments forming a closed rectangle suitable for extrusion or other 3D operations.

Inputs: input_data (required). Returns: object

add_sketch_constraintA

Add a geometric constraint/relation between sketch entities.

Creates geometric relationships between sketch entities such as parallel, perpendicular, tangent, coincident, etc. Essential for creating fully defined, parametric sketches that maintain design intent.

Inputs: input_data (required). Returns: object

add_sketch_dimensionA

Add a dimension to sketch entities.

Creates dimensional constraints that control the size of sketch entities. Dimensions are essential for creating precise, parametric designs that can be easily modified and maintain manufacturing tolerances.

In live SolidWorks automation, sketch dimensions can otherwise trigger the interactive Modify approval dialog. The adapter suppresses the relevant sketch-input preferences for the automation session and uses the dedicated radial/diameter APIs for circles and arcs so this tool remains non-interactive.

Inputs: input_data (required). Returns: object

add_splineA

Add a spline curve to the current sketch.

Creates a smooth, free-form spline curve that passes through or near the specified control points. Splines are ideal for creating organic shapes, complex profiles, and smooth transitions in industrial design.

analyze_drawing_annotationsC

Analyze drawing annotations and notes quality.

Inputs: input_data (required). Returns: object

analyze_drawing_comprehensiveC

Handle analyze drawing comprehensive.

Inputs: input_data (required). Returns: object

analyze_drawing_dimensionsB

Analyze dimensions in a SolidWorks drawing for consistency and completeness.

This tool performs detailed dimensional analysis including precision, tolerances, and completeness checking.

Inputs: input_data (required). Returns: object

analyze_drawing_viewsC

Analyze drawing views arrangement and quality.

Inputs: input_data (required). Returns: object

analyze_geometryC

Handle analyze geometry.

This tool provides various geometry analysis capabilities like curvature analysis, draft analysis, thickness analysis, etc.

Apply a template to an existing SolidWorks model.

This tool applies saved template settings including properties, dimensions, and formatting to the target model.

Inputs: input_data (required). Returns: object

arrange_dimensionsA

Move drawing dimensions so nothing overlaps, then check the real result.

Dimensions go outside their views in rows (first 8 mm from the outline, rows 7 mm apart, columns 9 mm apart), shortest span nearest the view, each on the side its extension lines start from. One with no room on that side stays put and is listed in unplaced. After moving them it re-reads every dimension's real text box and lines and checks the whole sheet: no text on text, no line through text, no line across another view or across its own view, nothing on a view or outside the sheet.

Inputs: input_data. Returns: object

auto_center_marksA

Auto-insert centre marks on circular features in a drawing view.

Runs SolidWorks' automatic centre-mark insertion for the named view. The API does not report how many marks it added, so the response gives the view's centre-mark count before and after and the delta. A run that added nothing is still a success — the view may have no un-marked holes.

Inputs: input_data (required). Returns: object

auto_dimension_viewC

Automatically dimension a drawing view.

Analyzes drawing view geometry and automatically adds common dimensions including overall sizes, hole diameters, radii, and critical features. Accelerates drawing completion and ensures comprehensive dimensioning coverage.

Inputs: input_data (required). Returns: object

automation_start_macro_recordingC

Start recording a macro in SolidWorks.

Begins macro recording to capture user actions and generate reusable automation scripts.

Inputs: input_data (required). Returns: object

automation_stop_macro_recordingA

Stop recording the current macro.

This tool stops the active macro recording and saves the recorded actions as a VBA macro.

Inputs: input_data (required). Returns: object

Check whether a sketch is fully defined.

Inputs: input_data. Returns: object

classify_feature_treeA

Classify the active model into a feature family from model-info and tree data.

This is a read-before-write helper for delegation. It summarizes whether the current document looks like a direct-MCP solid, sheet metal workflow, advanced VBA-backed part, assembly, drawing, or an insufficient-evidence case.

Inputs: input_data (required). Returns: object

close_modelA

Close the current SolidWorks model.

Closes the currently active SolidWorks document with an option to save changes before closing. This is essential for proper model lifecycle management and preventing data loss.

convert_file_formatB

Convert a SolidWorks file from one format to another.

Supports exporting source files to target formats such as STEP, IGES, STL, PDF, or other adapter-supported conversion outputs.

Inputs: input_data (required). Returns: object

create_assemblyB

Create a new SolidWorks assembly document.

Creates a new SolidWorks assembly document from template (a .asmdot path) or, without one, the default assembly template. The new assembly becomes the active document and is ready for component insertion, mating, and assembly-level operations.

Inputs: input_data (required). Returns: object

create_axisB

Create a reference axis along a principal direction.

Builds an axis from the intersection of two built-in planes: x from Top + Front, y from Front + Right, z from Top + Right.

Inputs: input_data (required). Returns: object

create_cut_extrudeA

Cut material from a sketch profile in the active model.

Creates a Cut-Extrude feature (Insert > Cut > Extrude). Use this after exit_sketch when you want to remove material — e.g. to create windows, holes, slots, or any through/blind cut in an existing solid body.

Sketch selection is never a silent guess: pass sketch_name explicitly whenever you're not certain which sketch this should act on (e.g. more than one sketch could be unconsumed, or other tool calls ran in between). If omitted, only the sketch most recently created/exited in this same session is used, and only when it still exists in the model — there is no further fallback. Any ambiguity or mismatch is reported back as an error naming the sketch(es) actually found in the model, rather than cutting the wrong profile.

Direction: a one-way cut (Blind or ThroughAll) goes along the sketch plane's normal. From a sketch on a face, or on a plane that touches the body only on one side (e.g. a Top Plane sketch under a block extruded up from it), that can point away from the material. The tool then cuts the other way and returns cut_extrude.direction_flipped: true, so you don't need to guess reverse_direction. For a sketch on a plane through the middle of the body, use ThroughAllBoth (or ThroughAll with both_directions) to cut both sides.

Inputs: input_data (required). Returns: object

create_detail_viewA

Create a detail view of a specific area.

Generates magnified detail views of specific regions to show fine features, tight tolerances, and intricate geometry that requires enhanced visibility for manufacturing and inspection.

Inputs: input_data (required). Returns: object

create_drawingB

Create a new SolidWorks drawing document.

This tool creates a new drawing document from template (a .drwdot path) or, without one, the default drawing template. The new drawing will become the active document.

Inputs: input_data (required). Returns: object

create_drawing_viewB

Create a drawing view of a SolidWorks model.

Creates technical drawing views including orthographic projections, isometric views, section views, and detail views from 3D models. Essential for generating production drawings and technical documentation.

Inputs: input_data (required). Returns: object

create_extrusionC

Create an extrusion feature from the active sketch.

Creates a 3D extrusion feature (boss or cut) from the currently active 2D sketch. Supports advanced options like draft angles, thin features, bidirectional extrusion, and various end conditions for professional modeling workflows.

Inputs: input_data (required). Returns: object

create_loftA

Creates a lofted boss/protrusion (Insert > Boss/Base > Loft) blending the listed profile sketches in order. Each profile must be a closed contour. Optional guide curves shape the transition between profiles.

Inputs: input_data (required). Returns: object

create_macro_libraryA

Create a library of organized macros for team sharing and reuse.

This tool sets up a structured macro library with categorization, documentation, and version control.

Inputs: input_data (required). Returns: object

create_partA

Create a new SolidWorks part document.

Creates a new SolidWorks part document from template (a .prtdot path) or, without one, the default part template. The new part becomes the active document and is ready for modeling operations such as sketch creation and feature addition.

Inputs: input_data (required). Returns: object

create_reference_planeA

Create a reference plane offset from an existing plane or planar face.

Adds a new plane to the feature tree, parallel to and offset from the named reference. The returned plane name can be passed straight to create_sketch to sketch anywhere other than the six built-in planes.

Angled planes are not supported by this tool: an angled plane needs a second reference (an axis or edge) to rotate about, which this signature cannot take. Use offset for parallel planes. An offset of zero is rejected — a plane coincident with its reference is not useful.

Inputs: input_data (required). Returns: object

create_reference_pointA

Create a reference point on the active part.

Two modes:

  • along_curve — a point on the edge under (x, y, z) mm, placed distance mm from the edge start, or at percent (0–100) of its length. Give exactly one of distance / percent.

  • face_center — a point at the centroid of the face under (x, y, z) mm.

The coordinate must lie on the target edge/face; SolidWorks resolves it with a coordinate pick. InsertReferencePoint always returns a feature, so success is confirmed by the feature tree growing.

Inputs: input_data (required). Returns: object

create_revolveB

Create a revolve feature from the active sketch.

Creates a 3D revolve feature by rotating the active 2D sketch profile around a specified axis of revolution. Supports full and partial revolves, thin features, and bidirectional revolution for comprehensive rotational modeling.

Inputs: input_data (required). Returns: object

create_section_viewC

Inputs: input_data (required). Returns: object

create_sweepA

Sweep the active profile sketch along a named path sketch.

Creates a swept boss/protrusion (Insert > Boss/Base > Sweep). Requires two sketches in the active part: a closed profile sketch and an open path sketch named by path. The profile is inferred as the sketch that is not the path (in the usual "draw profile, draw path, sweep" flow this is unambiguous). Optionally applies a constant twist along the path.

Inputs: input_data (required). Returns: object

create_technical_drawingB

Create a technical drawing from a SolidWorks part or assembly.

Supports selecting a template, output path, sheet format, scale, and optional auto- population of standard views for documentation.

Inputs: input_data (required). Returns: object

create_templateC

This tool creates templates for parts, assemblies, or drawings with standardized settings, materials, and configurations.

Inputs: input_data (required). Returns: object

delete_featureA

Delete a feature or sketch from the active model.

Deleting a parent feature also removes everything that depends on it — SolidWorks' normal cascade — so the response lists every feature that went, not just the one named.

Inputs: input_data (required). Returns: object

discover_solidworks_docsA

Discover and index SolidWorks COM and VBA documentation.

Creates a searchable index of all available COM objects, methods, properties, and VBA libraries for the installed SolidWorks version. Useful for building context for intelligent MCP tool selection and documentation queries.

Inputs: input_data. Returns: object

execute_macroA

Run a binary SolidWorks macro (.swp, or legacy .swb).

Calls ISldWorks::RunMacro2 on macro_path (or macro_file). Only binary macros run: VBA source (.vb, .bas, plain text) is rejected as invalid_input before anything reaches SolidWorks. The macro must not be interactive (no MsgBox or user forms).

Inputs: input_data (required). Returns: object

execute_workflowC

Handle execute workflow.

This tool executes a series of automated steps in sequence, with support for parallel execution and error handling.

Inputs: input_data (required). Returns: object

exit_sketchA

Exit sketch editing mode.

Exits the current sketch editing mode and returns to the 3D modeling environment. This is required after completing sketch geometry before creating 3D features like extrusions, revolves, or sweeps.

Returns: dict[str, Any]: A dictionary containing the resulting values.

Example: ```python # Complete sketch workflow await create_sketch({"plane": "Top"}) await add_circle({"center_x": 0, "center_y": 0, "radius": 5})

                result = await exit_sketch()
                if result["status"] == "success":
                    print("Sketch completed, ready for 3D operations")
                    # Now ready for extrude, revolve, etc.
                ```

            Note:
                - Must be called after sketch geometry creation
                - Required before executing 3D modeling operations
                - Automatically validates sketch geometry

                    print(f"Description: {doc['description']}")
                ```

            Note:
                - Requires an active SolidWorks document
                - Properties may vary based on document type
                - Some properties may be empty if not set
                - Technical properties depend on document configuration

Inputs: no named parameters. Returns: object

Returns a compact summary of the current model context that is useful for read-before- write LLM flows (document type, active configuration, and feature count).

Returns: dict[str, Any]: A dictionary containing the resulting values.

Inputs: no named parameters. Returns: object

get_selected_entitiesA

Report the faces/edges/vertices currently selected in the live SolidWorks UI.

Use this to find out exactly what the user has clicked on in SolidWorks before applying a feature (e.g. "chamfer the face I selected") instead of guessing from coordinates or a screenshot. Each entry includes enough geometry (bounding box, center, area/length, normal where applicable) to identify which face/edge is which, and the center coordinates can be fed straight into add_chamfer/add_fillet's "face:x,y,z" or coordinate edge_names syntax.

Returns: dict[str, Any]: entities (list of selection descriptors) and count on success.

Inputs: no named parameters. Returns: object

insert_bom_tableB

Insert a bill-of-materials table for an assembly view on the active drawing.

Inputs: input_data. Returns: object

insert_componentA

Insert a part or sub-assembly into the active assembly.

Call create_assembly first. Position is in millimetres from the assembly origin.

The component file must contain solid geometry — SolidWorks silently refuses to insert an empty part, so a missing or empty component surfaces as an error rather than a fabricated success.

Inputs: input_data (required). Returns: object

insert_model_dimensionsA

Bring the model's dimensions into the active drawing's views.

Imports the model's "marked for drawing" dimensions view by view, each dimension shown once on the sheet (a repeat in a later view is deleted). Pictorial views (isometric, dimetric, trimetric) are skipped unless named. Falls back to SolidWorks AutoDimension only when nothing could be imported. SolidWorks places imported dimensions inside the views, so run arrange_dimensions afterwards.

Inputs: input_data. Returns: object

list_available_materialsA

List materials in the installed SolidWorks material libraries.

Read-only; parses every .sldmat library SolidWorks is configured to use. Filter with search (name or classification substring, e.g. "steel" or "6061") and pass the exact name to set_material.

Inputs: input_data. Returns: object

list_componentsA

List the top-level components of the active assembly.

Returns: dict[str, Any]: Status and the component instance names.

Inputs: no named parameters. Returns: object

list_configurationsA

List configuration names for the active SolidWorks document.

Returns all available configuration names so callers can select a stable target before invoking feature or export operations.

Returns: dict[str, Any]: A dictionary containing the resulting values.

Inputs: no named parameters. Returns: object

list_drawing_viewsA

List the views on the active drawing.

Read-only. Use it to find an existing view's name before targeting it (e.g. with auto_center_marks). Errors when the active document is not a drawing.

Returns: dict[str, Any]: status, views (view names, sheet formats excluded) and count.

Example: python await list_drawing_views()

Inputs: no named parameters. Returns: object

list_featuresA

List feature-tree entries for the active SolidWorks document.

Useful for read-before-write workflows where the agent must inspect existing model structure before adding or editing downstream features.

Inputs: input_data (required). Returns: object

list_model_dimensionsA

List every dimension in the active part or assembly with its full name.

Read-only. Each entry's full_name (e.g. "D1@Sketch1") is the name set_dimension / get_dimension accept, so this is how to find and edit any driving dimension in an existing model. Pass feature_name to list one feature's dimensions only.

Inputs: input_data. Returns: object

list_open_documentsA

List every SolidWorks document that is currently open.

Read-only — does not change which document is active. Use it to discover what is open (an assembly plus its parts, a drawing plus its model) before switching with activate_document.

Returns: dict[str, Any]: status and documents — a list of {title, path, type, is_active} entries, plus count.

Example: python await list_open_documents()

Inputs: no named parameters. Returns: object

list_template_libraryB

List available templates from the template library.

This tool provides browsing and searching capabilities for the organization's template library.

lookup_api_interfaceC

List every indexed member (methods + properties) of a COM interface.

Inputs: input_data. Returns: object

lookup_api_methodA

Look up one SolidWorks API method or property by interface + name.

Confirms the member is indexed on that interface and returns its sibling members for context. The local index stores names only, so full signatures (parameters, return type) are not available here - use search_solidworks_api_help or help.solidworks.com for those.

Inputs: input_data. Returns: object

manage_design_tableB

Create or manage design tables for parametric modeling.

Design tables allow you to create multiple configurations of a part or assembly by driving parameters from an Excel spreadsheet.

Inputs: input_data (required). Returns: object

manage_file_propertiesB

Read, update, copy, move, rename, or delete file-related properties.

Uses the requested operation and file paths to manage SolidWorks file metadata or related file lifecycle tasks through the active adapter.

Inputs: input_data (required). Returns: object

measure_entitiesA

Measure faces, edges or vertices with SolidWorks' Measure tool.

One face gives its area and perimeter; one edge its length (and radius and diameter for an arc); two entities give the distance and angle between them. Entity coordinates are in metres. Clears the selection afterwards.

Inputs: input_data (required). Returns: object

mirror_featureA

Mirror solid bodies or features about a plane.

Selects the named sources and the mirror plane, then mirrors them. The mirror is verified by comparing model volume before and after: SolidWorks can report a feature even when it mirrored nothing, so a volume that did not grow is reported as an error rather than a false success.

Inputs: input_data (required). Returns: object

open_modelA

Open a SolidWorks model (part, assembly, or drawing).

Opens an existing SolidWorks file and makes it the active document for further operations. Supports all standard SolidWorks file formats and provides detailed model information upon successful opening.

Inputs: input_data (required). Returns: object

optimize_macroC

Optimize an existing macro for better performance and reliability.

This tool analyzes and suggests improvements to existing macro code.

Inputs: input_data (required). Returns: object

optimize_performanceC

Optimize SolidWorks performance settings.

This tool analyzes the current SolidWorks configuration and suggests or applies performance optimizations.

Inputs: input_data (required). Returns: object

pack_and_go_assemblyA

Copy a SolidWorks assembly and all its referenced parts to a self-contained folder.

Enumerates every component referenced by the active assembly, copies the assembly and each part into target_dir, then rewrites the stored component paths inside the copied assembly so it opens without any dependency on the original file locations — equivalent to the SolidWorks GUI Pack-and-Go operation.

Inputs: input_data. Returns: object

pattern_circularA

Pattern features around an axis.

Selects the named axis and features, then creates a circular pattern. The pattern is verified by comparing model volume before and after: SolidWorks can report a feature even when it patterned nothing, so a volume that did not grow is reported as an error rather than a false success.

Inputs: input_data (required). Returns: object

rebuild_modelA

Force a rebuild of the active model and report what is wrong.

Use after programmatic edits (set_dimension, feature edits) to confirm the model rebuilds cleanly. When features fail, the response is an error whose data.errors names each failing feature with its SolidWorks error code, the features/sketches it depends on, and a concrete hint for fixing it. Warnings alone still succeed.

Inputs: input_data. Returns: object

rename_featureA

Rename a feature on the feature tree.

SolidWorks silently refuses a rename onto a name another feature already uses, so the new name is read back and a mismatch is reported as an error rather than a quiet success. Renaming a feature to its current name is a no-op success.

Inputs: input_data (required). Returns: object

save_asB

Save the current model to a new location or format.

Saves the currently active SolidWorks document with a new filename, location, or file format. Supports multiple export formats for interoperability with other CAD systems and manufacturing workflows.

Inputs: input_data (required). Returns: object

save_assemblyA

Save the active SolidWorks assembly document.

Convenience wrapper that saves the currently active assembly. If no file_path is provided, saves to the existing location. Otherwise, saves as a new file.

Inputs: input_data. Returns: object

save_body_as_partA

Extract one solid body from the active multibody part to a new file.

Runs SolidWorks' Save Bodies on a single named body, writing a standalone part to file_path. The body is matched by name against the active part's solid bodies; the response lists every solid body found, so an unknown name reports the real options. Success is confirmed by the file existing on disk afterwards.

Inputs: input_data (required). Returns: object

save_fileA

Save the current SolidWorks model.

Saves the currently active SolidWorks document to its existing file location. Essential for preserving work and maintaining document version control. Handles both modified and unmodified documents based on force_save setting.

Inputs: input_data (required). Returns: object

save_partB

Save the active SolidWorks part document.

Convenience wrapper that saves the currently active part. If no file_path is provided, saves to the existing location. Otherwise, saves as a new file.

This tool helps when the LLM gets stuck by mapping user intent to discovered COM members and practical MCP workflow guidance.

Inputs: input_data. Returns: object

select_face_edgesA

Select every edge of one face of the active part (multi-select).

Identify the face with exactly one of point (a point on it, mm), side (top/bottom/front/back/right/left or +X..-Z; top=+Y, front=+Z, right=+X as in SolidWorks' default views - the furthest flat face facing that way) or plane (a reference plane name - the body face lying on it). edge_type narrows to linear or circular edges (e.g. hole rims).

The edges become the live SolidWorks selection, so the next add_chamfer / add_fillet call with an empty edge_names acts on exactly them. Anything that changes the selection in between (including the user clicking in SolidWorks) changes what is used.

Inputs: input_data (required). Returns: object

select_featureA

Select a named feature, sketch, plane or component.

Replaces the current selection by default; pass append: true to add to it (e.g. to select several features in turn). A name that cannot be selected is an error, never a quiet success.

Inputs: input_data (required). Returns: object

set_custom_propertyA

Create or overwrite one text custom property on the active document.

Typical names: PartNo, Description, DrawnBy, Revision. The value is read back after writing, so success means it was stored.

Inputs: input_data (required). Returns: object

set_dimensionA

Set the value of a dimension in the current model.

This tool modifies the value of a named dimension and rebuilds the model. Use this to parametrically modify your model dimensions.

Inputs: input_data (required). Returns: object

set_materialA

Assign a library material to the active part.

The material drives mass properties (get_mass_properties) and what a title block's Material field shows. The name must match the library exactly; find it with list_available_materials. The material is read back after assignment, so success means it really applied.

Inputs: input_data (required). Returns: object

set_sheet_scaleB

Set the active drawing sheet's scale; views using the sheet scale follow.

Inputs: input_data. Returns: object

set_unitsA

Set the active document's linear unit system.

Accepts mm, cm, m, in or ft (plus common aliases such as inch or millimeters). The setting is applied and then read back from the document; if the readback disagrees the tool reports an error rather than a false success.

Inputs: input_data (required). Returns: object

sketch_circular_patternA

Create a circular pattern of sketch entities around the sketch origin.

Generates a circular array of selected sketch entities. The rotation axis is always the sketch origin — SOLIDWORKS' CreateCircularSketchStepAndRepeat does not expose a pattern-centre parameter. Position the seed entity at the desired radius from the origin; the pattern derives its radius from the seed's centre.

Essential for creating bolt circles, gear teeth, and other radially symmetric features around the sketch origin.

Inputs: input_data (required). Returns: object

sketch_linear_patternB

Create a linear pattern of sketch entities.

Generates a linear array of selected sketch entities in specified direction(s) with defined spacing and count. Essential for creating hole patterns, vent grilles, and repetitive geometric features.

Inputs: input_data (required). Returns: object

sketch_mirrorA

Mirror sketch entities about a centerline.

Creates mirrored copies of selected sketch entities about a reference centerline, maintaining symmetrical design relationships. Essential for creating symmetric parts and reducing modeling time.

Inputs: input_data (required). Returns: object

sketch_offsetA

Create an offset of sketch entities.

Generates offset copies of selected sketch entities at a specified distance, maintaining the original entity shape while creating parallel geometry. Essential for wall thickness, machining allowances, and clearance features.

Inputs: input_data (required). Returns: object

sketch_tutorial_simple_holeA

Tutorial: Create a simple circular hole sketch.

Demonstrates complete workflow for creating a basic hole sketch that can be used for through-holes, counterbores, or other circular features. This tutorial shows the fundamental sketch-to-feature process.

Returns: dict[str, Any]: A dictionary containing the resulting values.

Example: ```python # Learn basic sketching workflow result = await sketch_tutorial_simple_hole()

                if result["status"] == "success":
                    print("Tutorial completed successfully!")
                    print("Steps performed:")
                    for step in result["steps"]:
                        print(f"  - {step}")
                    print(f"Next: {result['next_steps']}")
                ```

            Workflow:
                1. Creates sketch on Top plane
                2. Adds 2.5mm radius circle at origin (5mm diameter hole)
                3. Exits sketch editing mode
                4. Returns sketch ready for extrusion or cutting operations

            Note:
                - Demonstrates complete sketch creation workflow
                - Creates standard 5mm diameter hole geometry
                - Result is ready for negative extrusion to create hole
                - Perfect starting point for learning SolidWorks automation

Inputs: no named parameters. Returns: object

start_macro_recordingA

Start recording a SolidWorks macro.

This tool initiates macro recording to capture user actions for later playback and automation.

Inputs: input_data (required). Returns: object

stop_macro_recordingA

Stop macro recording and save the recorded macro.

This tool stops the active recording session and saves the generated macro code to a file.

Inputs: input_data (required). Returns: object

suppress_featureA

Suppress or unsuppress a feature in the active model.

Suppressing rolls a feature and its children out of the model without deleting it — the reversible way to turn off a feature that is causing trouble.

Inputs: input_data (required). Returns: object

tutorial_simple_holeA

Create a simple hole as a guided tutorial workflow.

Builds a sketch circle on the selected plane, exits the sketch, and creates a cut feature using the supplied diameter and depth. Useful as an end-to-end example of a basic subtractive feature.

Inputs: input_data (required). Returns: object

undoA

Undo the last operations in the active model.

SolidWorks accepts an undo with nothing left to undo without complaining, so the response reports whether the feature tree actually changed rather than assuming it did.

Inputs: input_data. Returns: object

update_sheet_formatC

Update the sheet format and title block information.

Applies drawing templates and updates title block fields with project information, revision data, and drawing metadata. Essential for standardized documentation and drawing control.

Inputs: input_data (required). Returns: object

update_title_blockB

Update title block fields for the active drawing.

Applies drawing metadata such as title, drawing number, and approval fields to keep documentation aligned with standards.

Inputs: input_data (required). Returns: object

validate_drawing_completenessC

Validate drawing completeness for production readiness.

Inputs: input_data (required). Returns: object

verify_modelA

Check the active part or assembly against what you meant to build.

Call this as the last step of a build (and whenever a step looks suspicious). A modelling tool returning success does not prove the geometry is right; this reads the model back and compares it with your expectations. Give only the expectations you know; each becomes one check. With no expectations it just reports what it measured.

Units: mm, mm³ and kg. bounding_box_mm is the overall size [x, y, z] in model axes (a sketch on the Front Plane extrudes along z). Widen relative_tolerance when your hand calculation ignores fillets or chamfers, and length_tolerance_mm when measured.bounding_box_method is assembly_box (SolidWorks' assembly box can be slightly larger than the parts). Mass depends on the assigned material; without one SolidWorks uses a default density.

Each check reports expected, actual, tolerance and passed: true, false, or null when the value could not be measured (never counted as a pass). verdict is pass, fail, inconclusive (nothing failed, something unmeasured) or report_only. status stays success when the model does not match: the tool worked, the model is what failed.

Inputs: input_data. Returns: object

    C2.7/5.0

    Scored across 154 tools

    Disambiguation2/5

    Many tools are functionally indistinguishable or duplicate aliases: get_mass_properties is literally a 'backward-compatible alias' for calculate_mass_properties, start_macro_recording/stop_macro_recording duplicate automation_start_macro_recording/automation_stop_macro_recording, batch_process_files vs batch_file_operations vs batch_export vs convert_file_format heavily overlap, and create_drawing / create_technical_drawing / generate_drawing_package all claim to produce drawings. add_dimension vs add_sketch_dimension vs insert_model_dimensions vs auto_dimension_view and the seven analyze_drawing_* / check_drawing_* tools are also hard to separate. Only the core sketching and modeling primitives (add_line, add_circle, exit_sketch, create_sketch) have clearly distinct purposes.

    Naming Consistency3/5

    The dominant pattern is snake_case verb_noun (create_part, export_step, add_fillet), which is good, but there are notable deviations: adjective-suffixed names like analyze_drawing_comprehensive and analyze_geometry ('Handle analyze geometry'), prefix variants automation_start_macro_recording vs start_macro_recording, noun-first tutorial names (sketch_tutorial_simple_hole vs tutorial_simple_hole), and several bare/ambiguous verbs (undo, save_as). The parallel generate_vba_* family is consistent, but the duplication of naming across prefixes suggests two conventions merged.

    Tool Count1/5

    154 tools is an extreme mismatch for a single MCP server — roughly ten times a well-scoped surface. Whole clusters (11 generate_vba_* tools, 9 analyze_drawing_* tools, a macro recording API duplicated twice, a template library suite, and an API-doc lookup suite) could be collapsed or moved out. Many of these tools clearly do not earn their individual place.

    Completeness4/5

    Coverage of the CAD lifecycle is genuinely broad: document creation/open/save, sketching primitives, boss and cut features, fillets/chamfers/patterns/mirror, assemblies with mates and interference checks, drawings with views, dimensions, GD&T and BOM, mass properties, and many export formats. Minor gaps exist — mating is limited to reference planes/axes, angled reference planes are unsupported, and no couple-level assembly mirror, but no major workflow dead end.
