Sorry, I have rejoiced to soonHypercube3D wrote: ↑Sun Jul 18, 2021 11:10 amIt seems to import OK, but when I check scale, its x1000 and impossible to scale or do decent operations such as export as STEP or cut with the Part > Slice Apart tool (crashes). Tried under different OS and versions of FreeCAD with something as simple as a sphere generated in blender + repaired top and bottom into quad faces (still crashes). Workflow ok with f360 (but not perfect as shapes get more complex).jeno wrote: ↑Sun Jul 18, 2021 8:30 am To shorten things up, it is much better to work with fbx-format. It supports quads. Export from Blender to fbx. Use Cad Assistant to import the fbx (the free version is fine). Save it in Cad Assistant as BREP-file. You can import BREP directly in Freecad. All quads stay alive.

I think the scale is x100 (default unit Blender 1m <> default unit fbx 1cm). Blender offers an scale option for FBX export in transform section When I check the geometry of the imported brep I got an error. It says it is not a surface. The output is
Code: Select all
Shape type: Compound
Vertices: 0
Edges: 0
Wires: 0
Faces: 1
Shells: 0
Solids: 0
CompSolids: 0

I digged a bit deeper. Cad Assistant runs with opencascade 7.6.0dev. Maybe this causes the issue.
Blender works with meshes. The quad (or tri) is flat. I guess in case it is transformed to any kind of spline or whatever the region of a certain quad wil still be flat. So it is difficult to decide what it is.Hypercube3D wrote: ↑Sun Jul 18, 2021 11:10 am ...
I have doubt about the quad faces showing in import - seems the whole idea of T-splines and smooth infinite resolution surfaces lost because it still seems like a polygon mesh made solid.
