How to precisely fillet edges in this case?

Hi,
I would to know is it possible to fillet (cove) edge between these two unregular obejcts
(model with specific and complex surface from 3ds).

Hi keu - FilletSrf should get that.

Thanks! Itā€™s working! But only one to one polygon connecting. How to force these all?

Hello- polygons are not involved here, as far as I can see - only surfaces, but if I understand you, you may want to Join the surfaces and use FilletEdge.

a file would make is easier to see what the issue is, less guessing involved. also what software are you using actually? that does not look like rhino if i am not mistaken

Oh, okay. I just imported obj file and transformed it by command ā€œmesh to nurbsā€, and it made polysurface.

Itā€™s just screenshot from Max. Iā€™ve imported obj from max and used ā€œmesh to nurbsā€. Then tryed to filled surfaces, as Pascal said, but it seems like only one polygon on one surface could be selected.

a nurbs derived from a mesh will have polysurfaces, that is for fileting not a good start. better would be if you`d rebuilt that curved wall with a nurbs line then extrude and trim. all those little lines you have here are now separate surfaces you want these to be one

Could you write step by step solution? Iā€™m just newbie student with not too much time for make model. :slightly_frowning_face:

Hello - please see the training material above - making good, or even reasonably decent surfaces from meshes is not, generally, a simple task that someone can just ā€˜doā€™ for the asking. Asking for a step by step solution to this compex problem is not reasonable. Youā€™ll need to learn Rhinoā€¦ no way around it - if you want to reverse engineer meshes. You might look into SubD workflows though, these can be helpful in getting ā€˜smoothā€™ objects from meshes. Quadremesh may also help.
