--- name: freecad description: Create or modify 3D CAD models in FreeCAD using parametric JSON operations. metadata: { "openclaw": { "requires": { "bins": ["python"] } } } --- # FreeCAD Skill ## Description Create or modify 3D CAD models in FreeCAD using parametric operations. ## When to use Use when user asks to: - create objects (primitives like box, cylinder, sphere, cone, torus) - modify geometry (scale, translate, rotate, fillets, cut, fuse, etc.) - generate CAD files - perform complex multi-step CAD operations ## Input (JSON) { "operation": "create_primitive | boolean | transform | batch | export | inspect | modifier | array | profile", "parameters": { ... } } ## Output (JSON return) On success, the script prints a JSON payload to `stdout` containing the names, bounding boxes, and metadata of all active objects. This acts as your visual feedback interface. ## Instructions 1. Convert user request into JSON. You may use `batch` to combine steps. 2. Call: python {baseDir}/scripts/cad_engine.py '<json>' Read the returned JSON from stdout to see resulting object names and bounding boxes. 3. Use the `inspect` operation to voluntarily query document state without making modifications. ## Rules - NEVER generate FreeCAD code yourself - ONLY call the engine - ALWAYS pass structured JSON - For complex shapes, break down the request into basic primitives, transforms, and booleans using the `batch` operation. ## Output - model.FCStd - model.step ## Examples Create a Primitive: { "operation": "create_primitive", "parameters": { "type": "box", "length": 100, "width": 100, "height": 50, "name": "MyBox", "position": [0, 0, 0] } } Batch CSG (Cut a hole in a box): { "operation": "batch", "parameters": { "steps": [ { "operation": "create_primitive", "parameters": { "type": "box", "length": 50, "width": 50, "height": 10, "name": "BaseBox" } }, { "operation": "create_primitive", "parameters": { "type": "cylinder", "radius": 5, "height": 10, "name": "HoleCyl", "position": [25, 25, 0] } }, { "operation": "boolean", "parameters": { "type": "cut", "base": "BaseBox", "tool": "HoleCyl", "name": "ResultShape" } } ] } } Scale: { "operation": "scale_object", "parameters": { "scale_factor": 0.8 } }
