Part design workbench: Fillet fails / not generating correctly with drafted walls

[Miksu80]

When doing drafted walls and adding fillets to them, they're not correctly generated:

Can confirm.
Sometimes joining with Refine TRUE helps to avoid those situations, but this seems to be a bug indeed.

confirmed, but I think that this new function of tapper angle is still experimental. Not only this bug happens with it. I encourage the developers an @realthunder for their efforts. I think that they are working on it.

Yep, tested with cuts and it works, don't know that does it fail with drafted walls..

I know that bug squashing is a basic part of sw development -> I've been squashing bugs with commercial cads also. Realthunder and other active members do a superb job and I enjoy using FreeCAD :)

Just tested 2nd fillets around the part in previous post and it fails:

The issue shown red in capture is not related to issue but its because I selected a line to show what has been selected when doing fillet. I've had the same error also when using mirror with complicated part but didn't make an issue because of it was not very simple shape.
