Get general information about the currently open SketchUp model: name, file path, unit system, entity/layer/material counts.

List all layers (tags) in the SketchUp model with their visibility.

List all materials in the SketchUp model with their colors and textures.

List entities (faces, edges, groups, component instances) in the model or inside a named group.

List all component definitions in the SketchUp model.

Create a flat face (polygon) in SketchUp from an ordered list of 3D points. Points are in SketchUp's default unit (inches unless model is metric).

Create a line segment (edge) between two 3D points.

Create an empty named group in SketchUp, optionally on a layer.

Create a 3-D box (rectangular prism) by specifying width, depth, height. Optionally provide an origin [x, y, z] for the base corner.

Create a circle in SketchUp from a center point, normal vector, and radius. Returns edges forming the circle.

Create an arc in SketchUp. Specify center, radius, start/end angles in degrees.

Create a regular polygon (triangle, pentagon, hexagon, etc.) with n sides.

Push/pull a face by a specified distance. Positive distance extrudes outward, negative pulls inward.

Extrude a face along a path (array of edge IDs). This is SketchUp's Follow Me tool.

Move (translate) an entity by a vector [x, y, z].

Rotate an entity around an axis by a given angle in degrees.

Scale an entity. Provide a single number for uniform scaling, or [x, y, z] array for non-uniform scaling.

Create a new (empty) component definition and place one instance in the model. Returns the definition name and instance ID.

Place an instance of an existing component definition into the model at a given origin.

Create engineered roof trusses with accurate geometry based on professional truss analysis. Supports king post (simple, up to 26') and fink/W-truss (most common, 20-60'). Trusses include proper web patterns, angled members, and realistic connections. Use construction://roof-trusses resource for detailed guidance.

Execute arbitrary Ruby code inside SketchUp. The code runs in the context of the SU_MCP module and has full access to the SketchUp Ruby API (Sketchup, Geom, UI, etc.). Returns the result of the last expression and any puts/print output. Use with care — this can modify or delete model data.
