i attached the file i tried to load. BallAndCube.zip

s-light commented 2 years ago

fixed with #8

KeithSloan commented 2 years ago

As you say in #8 the Brep shape is handled but the extrusion of the PolylineCurve is NOT.

I am unsure if I should be calling ToNurbsCurve or ToPolyLine and how to test, do you have an image of object so I see what sort of line is being extruded.

s-light commented 2 years ago

thanks for looking into it! i check tomorow if i have a image of the result...

s-light commented 2 years ago

i only have the - also included in the zip file - step BallAndCube.stp. imported in FreeCAD it looks like this: image
