CAD Skill
Generate 3D CAD models programmatically using CadQuery (Python) with Blender rendering.
Quick Start
# Generate a model from description
~/.claude/skills/cad/scripts/cad-generate "box with 4 mounting holes"
# Render an existing STL
~/.claude/skills/cad/scripts/cad-render /path/to/model.stl
# List example templates
~/.claude/skills/cad/scripts/cad-generate --list-templates
Capabilities
- Parametric modeling: Dimensions, hole patterns, arrays all adjustable
- Export formats: STL (3D printing), STEP (CAD interchange)
- Rendering: Blender Cycles GPU rendering for previews
- Common parts: Brackets, enclosures, mounts, spacers, adapters
Architecture
User prompt → Claude generates CadQuery Python → Execute → STL/STEP
↓
Blender render → PNG
Python Environment
Uses dedicated venv at ~/.venvs/cad with Python 3.12:
- cadquery (parametric CAD)
- cadquery-ocp (OpenCASCADE kernel)
Example Code
import cadquery as cq
# L-bracket with mounting holes
result = (
cq.Workplane("XY")
.box(50, 30, 5) # Base plate
.faces(">Z").workplane()
.move(0, 12.5)
.box(50, 5, 40, centered=(True, True, False)) # Vertical
.faces("<Z").workplane()
.pushPoints([(-15, 0), (15, 0)])
.hole(5) # Mounting holes
)
cq.exporters.export(result, "bracket.stl")
cq.exporters.export(result, "bracket.step")
Common Patterns
Hole Arrays
.pushPoints([(x, y) for x in [-20, 0, 20] for y in [-10, 10]])
.hole(diameter)
Fillets (rounded edges)
.edges("|Z").fillet(radius) # Vertical edges
.edges(">Z").fillet(radius) # Top edges
Shell (hollow out)
.shell(-wall_thickness) # Negative = outward, positive = inward
Extrude with taper
.extrude(height, taper=5) # 5 degree draft angle
Rendering
Uses Blender Cycles with:
- GPU acceleration (Metal on macOS)
- 64 samples for quick preview
- Blue metallic material
- Dark background
Limitations
- No GUI preview (headless only)
- Fillets can fail on complex geometry (use simpler shapes)
- Large models may take longer to render
Output Locations
- STL/STEP:
/tmp/cad_output/(timestamped) - Renders:
/tmp/cad_output/(PNG)
