Seamless CAD¶
Non-destructive CAD modelling inside Blender.
Shapes are computed by OpenCASCADE (OCCT), not by Blender's mesh system, and the result is drawn in the viewport. Primitives, booleans, fillets and chamfers are kept as a Feature Tree — a history you can go back and re-edit at any time. Move a proxy with G / R / S and the geometry follows in real time.
Output goes two ways: Bake to Mesh for use inside Blender, or Export STEP for a real B-Rep file other CAD software can open.
Beta. Sold for Windows. macOS (Apple Silicon) and Linux builds exist and are being given to testers, but are not a product — see Testing builds and Known limitations.

| Turn a sketch into a solid | Sketch, constrain, apply, and give the result thickness |
| Cut holes and pockets | Booleans, patterned holes, rounding the edges |
| Exchange files with other CAD | Getting a part out to SolidWorks, Fusion or FreeCAD, and back |
