Open engineering, for everyone.
CommunityCAD exists to democratize engineering design. We believe access to quality CAD models, technical datasheets, and peer validation should not be locked behind paywalls or proprietary ecosystems. So we built a free, community-driven library where engineers share, discover, and validate the parts they build with.
What we stand for
Open access
Engineering knowledge should be freely shared and built upon — not locked behind paywalls or proprietary ecosystems.
Community validation
Accuracy scores and peer review make models trustworthy, so you can build on parts you can actually rely on.
Format freedom
We support open formats (STEP, STL, OBJ, DXF, FreeCAD) right alongside proprietary ones like SolidWorks and Fusion.
Creator empowerment
Creators keep ownership of their work and get direct support from the community through donations.
Who we serve
- Students learning CAD and mechanical design
- Hobbyists and makers sourcing parts to print or build
- Independent engineers who need reliable references fast
- Small businesses and manufacturers without enterprise licensing budgets
How it works
Discover
Search thousands of community and partner models with text or AI-powered semantic search.
Download
Grab the format you need — free. Datasheets and multiple versions live right on the model page.
Share & validate
Upload your own models, score the accuracy of others, and help the library get better for everyone.
Built in the open
CommunityCAD is built with open-source tools, and we plan to open-source the platform itself. Engineering should be collaborative — and so should the tools we build it with.
