Hi Heiner, thanks for attaching the model, it's really late over here so I'll try to check it out tomorrow.

It is available in v2 as well, but I'd really very strongly recommend working in the current v3 beta instead of v2, there have been a whole lot of bug fixes implemented in v3 including many for filleting.
