The Surface workbench provides tools to create and modify surfaces. It has a very similar functionality as Part Shape builder Face from edges, but it is parametric and provides additional options. Its features are:

  • Create surfaces from boundary edges
  • Align the curvature from neighbor faces
  • constrain surfaces to additional curves or vertexes.
  • extend faces (need to find out how!)
  • curves on meshes?

introduced in version 0.17

Surface Tools

  • Filling...: fills a series of boundary curves, constraint curves and vertexes with a surface

Additional Menu Tools

These tools are only found in the Surface menu.

How to use

Limitations

The used surface code from the CAD-kernel OCCT is very fragile and can not handle wrong input properly. This can cause FreeCAD to crash. The following situations cause problems and may crash FreeCAD:

  • adding additional edges or wires as boundary to a surface, that would make up several faces. Add those edges only to Unbound Edges
  • Using of boundary edges, that fails do build a closed boundary at parametric changes of the document.
