Post by PelleH »

Hi,
I have one little problem cutting in sweep forms. When I subtract one form from the sweep it will crack.
Here are before cutting. The cone should be cut off.

it is often only a visual defect, if you do a subtractiv pipe, in general it works
but without file, no definitive answer

FreeCAD is parametric, so it's sufficient to upload one of the files instead of three.

It works in PartDesign. We have seen this before, that the helical sweeps behave differently in both workbenches.
