What is mesh2cad?

mesh2cad fits analytic surfaces to a triangle mesh and rebuilds a valid B-rep solid you can select and dimension in FreeCAD, Fusion or Onshape. Simple mechanical parts can also come back as a parametric CadQuery, OpenSCAD or FreeCAD script, so changing a hole diameter is one number. A fidelity report says how close the result is to the mesh, and it falls back to a valid faceted solid instead of guessing when a fit is bad. Free-form surfaces are not supported. MIT licensed, pure Python on top of OpenCascade.
