# 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](https://www.freecad.org/) (PartDesign, TechDraw, Path) | Full parametric CAD | Feature tree, assemblies, CAM, Python API | Active | 
| [SolidCraft](https://github.com/bherbruck/solidcraft) | Parametric 3D CAD | MCP server, Rust, WASM, constraint solver | Active | 
| [CADRS](https://github.com/rvdende/cadrs) | Onshape-style CAD | OpenCASCADE kernel, MCP, assemblies, drawings | Early | 
| [OpenCADStudio](https://github.com/HakanSeven12/OpenCADStudio) | 2D/3D hybrid | Native DWG/DXF, GPU rendering, MCP | Active | 
| [SolveSpace](https://solveSpace.org/) | Parametric 2D/3D | Lightweight, constraint solver, STEP export | Active | 
| [OpenSCAD](https://openscad.org/) | 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
