Find installed SOLIDWORKS versions, CAM/add-in registrations and API libraries; no app launch.

Attach to SOLIDWORKS 2025 (revision 33); launch=true may start it. Returns an app handle.

Invoke any exposed COM member. Use {$ref:handle}, {$variant:'I4',byref:true,value:0}, typed arrays with array:true, {$missing:true}, or {$bytes:base64}. Returns value and out_args. Get managers with action=get. Explicit action avoids confusing methods and properties. This is full API access: calls may modify documents, execute macros, or access local files.

Execute ordered API steps without interleaving. Reference earlier results with {$result:'step_id',path:['value','$ref']}. Stops at first error and reports completed steps; earlier mutations remain applied. This is not a rollback transaction.

Read a page of an array returned as an object handle; preserves every item of large arrays.

Release unneeded session handles on their COM apartment. Does not close documents.

Index a local vendor .tlb/.dll API library without registering it; find paths with discover.

Search loaded API libraries for CAD/CAM interfaces, exact methods, parameters and enums. Load installed sldworks.tlb, swconst.tlb, camworks.tlb or an add-in DLL first.

Return the active document handle, title, path and document type without changing it.

Read configured default part, assembly and drawing template paths.

Create a part/assembly/drawing from an absolute existing template path; returns its handle.

Open an absolute part(1), assembly(2), or drawing(3) path. Returns COM errors/warnings.

Save/export by extension inside workspace (SLDPRT, SLDASM, STEP, STL, PDF, etc.). Format support depends on document type. For export options use API SaveAs with ExportData.

Rebuild a model, reporting failure. Inspect features afterwards for individual error codes.

Inspect bounded feature tree with feature types and error/warning codes.

Inspect assembly occurrences, parent relationships, suppression and transforms, with bounds.

Compute model mass/volume/area and inertia using current material and configuration.

Legacy convenience: create/select a 2D sketch on a plane and add a batch of simple entities in one call (line/circle/rectangle). For the full entity/relation/dimension set, use solidworks_sketch's operation dispatch (begin/add_entities/fillet/chamfer/... /exit).

solidworks_reference_geometry: dispatches on payload.operation to one of the capability-module handlers for [axis, coordinate_system, coordinate_system_numeric, plane, point].

Encode an entity's persistent reference for reacquiring it after edits or reopening its model.

Resolve a persistent reference in its original document; reports deleted/invalid entities.

Edit a feature's definition with AccessSelections/ModifyDefinition. Discover exact properties in its feature-data interface. Use generic API or scripts for indexed/method-based definitions.

Attach to the installed SOLIDWORKS CAM add-in and GetCWApp API. Optional exact GUID/ProgID. Add-in presence is distinct from API/license availability; inspect returned status.

Report observed CAM connection state; never treats an installed library as a license.

Legacy low-level CAM action/args dispatcher retained for the small set of raw CAMService.workflow actions (active_document, machine, stock, set_machine, stock_box, recognize_features, operation_plan, toolpaths, postprocess, license) that back the typed solidworks_cam grouped tool's operations. Prefer solidworks_cam -- it exposes the full CAM operation surface (list_machines, define_stock, generate_operation_plan, set_tool, generate_toolpaths, post_process, ...) with proper per-operation schemas.

Execute trusted Python on the COM apartment (--allow-scripts required). Globals: sw, cad, cam, gateway, call(obj,member,*args), workspace, parameters. Assign result. Supports loops, equations, advanced features, assemblies and arbitrary add-ins. Full local code execution, not a sandbox. Prints are captured. Background jobs allow lengthy CAD/CAM computation.

Poll job state/result without entering the busy COM queue. Failed jobs may have partial effects.

Cancel a queued job only. A running native SOLIDWORKS call cannot be safely aborted.
