Score: 8.3/10 (Innovation: 8, Technical: 9, Documentation: 9, Utility: 7)

hackerscad is a parametric CAD tool that uses a C-like scripting language (subset of D) for solid modeling with OpenCascade B-rep, offering an editor with mouse-driven operations that write back to code, AI agent integration via MCP, and extensive libraries for mechanical parts. It's interesting as a code-first CAD alternative to OpenSCAD, adding fillets, constrained sketches, and a language that leverages existing editor and AI knowledge.

Target audience: mechanical engineers, makers, 3D printing enthusiasts, developers interested in CAD, AI agent users
