ExtrudeSrfTapered trouble

I’m taking a surface, cutting a rectangle into it, and using ExtrudeSrfTapered on it, and this is the result. It always happens in one corner.

However, if I use it on new geometry, it seems to be working.

Any ideas?

Also: ExtrudeCrvTapered, new curve vs. curve in rectangle created with Split:


Hello - try SimplifyCrv on the input - does that clean up?


Hey Pascal -

I can’t seem to apply it to the curve(s) I’m extruding.

Hello - in the case of the surface edges, you’ll want to DupEdge, Join, then extrude to get the corners to work out, otherwise they are treated as individual lines.


Got it - thanks again.
