Hello everyone, I do not know if you have encountered this situation?
BRepOffsetAPI_MakePipeShell from a spine of bsplinecurve and a profile of circle, but strange results appeared. See Figure 1 and Figure 2 specifically.
I don't know how to eliminate this problem. In addition, but if the spine is a line or arc or circle or ellipse, it's ok.
The code I created is as follows.
Thank you all.
