Mechanical & Product Design PRIMARY FOCUS
This is our primary benchmark category. Open-source tools for parametric 3D mechanical design, assemblies, CAM/CNC workflows, and technical drawing production. Focus on constraint-based modeling, feature trees, and manufacturing-ready output.
Tools We Actively Test
| Tool | Type | Strengths | Status |
|---|---|---|---|
| FreeCAD (PartDesign, TechDraw, Path) | Full parametric CAD | Feature tree, assemblies, CAM, Python API | Active |
| SolidCraft | Parametric 3D CAD | MCP server, Rust, WASM, constraint solver | Active |
| CADRS | Onshape-style CAD | OpenCASCADE kernel, MCP, assemblies, drawings | Early |
| OpenCADStudio | 2D/3D hybrid | Native DWG/DXF, GPU rendering, MCP | Active |
| SolveSpace | Parametric 2D/3D | Lightweight, constraint solver, STEP export | Active |
| OpenSCAD | Script-based CAD | Code-first, reproducible, libraries (BOSL2) | Active |
Test Categories (Active)
- Modeling speed — Sketch → constrain → feature benchmark
- Assembly handling — Mate constraints, motion, BOM
- CAM workflow — Toolpath generation, G-code quality
- Drawing automation — TechDraw views, dimensions, export
- STEP/IGES fidelity — Round-trip with commercial CAD
- Large assembly performance — 100+ parts, regeneration time
