CAD Forge

Describe a part. Get real CAD.

Not a mesh guess: a parametric build123d program that the OpenCascade kernel has accepted, with exact dimensions you can change, STEP for engineers and STL for printers.

Name the part, the key sizes, and how it mounts. Ctrl Enter to forge.
  • Kernel-checkedEvery part is built on OpenCascade before you see it. Errors go back to the writer until it builds.
  • ParametricKey dimensions become sliders. Each configuration rebuilds and gets its own link.
  • Yours to keepDownload STEP, STL, GLB, a drawing sheet, and the Python program itself.
