I think there are two separate issues :
- FreeCAD has an underlying weakness regarding internal topological identification. Basically, vertices, edges and faces are assigned ID numbers randomly. When you change a property, the object is recomputed, and if the number of faces changes, then the previously existing faces see their ID change. This is why you see unexpected results when you change the gap properties of BendRight. The following bends are not aware that the ID of the face to which they were applied has changed. So they try to apply themselves to totally different faces. (Currently, two FreeCAD developers are working on solutions to address that, but it will take time before the solutions are implemented in FreeCAD).
- The Sheet Metal workbench add-on does not provide a way to reassign a bend to a different face, which would allow you to repair the model. This could be a feature request to https://github.com/shaise/FreeCAD_SheetMetal/issues
Good morning all,
Thank you for your fulfilling response to this issue for modifing and editing bends designed with the sheet metal workbench.
If I understand correctly, bends are currently not editable nor in the 1) part workbench or 2) part design workbench?
In addition, the sheet metal workbench unfold functionality is sensitive to the way cuts are implemented in bends. Somehow, the unfold feature is not working with cuts made with the part workhench, see example here which fails to unfold (https://rushfiles.one/client/publiclink ... zPtZF46QMV
). suggestions for introducing cuts are very welcome.
