Score: 6.8/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 6)

DiffCAD is a FreeCAD workbench that enables reviewing parametric model changes similarly to code diffs, using git-integrated snapshots. It fills a known gap in CAD version control by providing hierarchical and property-level diffing, making it interesting for collaborative design workflows.

Target audience: mechanical engineers, cad designers, open-source hardware developers
