Rhino WIP has many improvements to the fillet and chamfer commands: FilletSrf, ChamferSrf, FilletSrfCrv, and FilletSrfToRail Continue across faces option for FilletSrf and ChamferSrf. Simplified (revolved) surface for FilletSrf and ChamferSrf where possible. Interactive Dialog for ChamferSrf. Bett…

I don’t think it is really our place to comment on Parasolid or licensing issues with that library. I would recommend asking that question to Plasticity. Rhino uses a library for these geometric calculations that we (McNeel) have written and maintain.

Hi Menno, do you think this fur face replacement also applies to other solid editing requests? Should this surface replacement be use more broadly for model edits, not just fillets? G

Yes, that is probably a good idea. Commands like Trim, Intersect, Booleans, Fillets etc. could all benefit.

[image] Menno Deij - van Rijswijk: It is better to replace that with a trimmed planar surface. workflow/workaround: for a closed solid: subselect (ctrl / cmd + shift + click), delete _cap would be nice to have this feature in _mergeAllCoplanarFaces (maybe as option) EDIT: and also in…

If this ever gets implement, please consider automatically putting the scrapped original surface into a dedicated layer (Scrapped geometry) or at least put a warning message into the Command line. :slight_smile: Losing the original geometry after running certain command could bring some headache to …

[image] Menno Deij - van Rijswijk: FilletSrfCrv [image] Menno Deij - van Rijswijk: FilletSrfCrv in Rhino 9 WIP: [image] would be nice if surfaces of revolution (torus / tori) are found as such. (similar to filletSrf - but this was solved as far as i followed) great to see inproveme…

I agree, that will need some re-factoring and re-thinking on how these revolved surfaces are created. Currently the method requires both ends of the surface to be associated with a surface; for FilletSrfCrv that is obviously not the case. I made this YT RH-88865 .

F-I-N-A-L-L-Y! :smiley: This have been requested a gazillion times in so many topics. Simple revolved fillets should be simple revolved fillets, instead of random surfaces with a huge amount of control points.
