Hi Micheal I have a little issue on beveling a solid imported from Blender but I had no problem to perform the bevel with FreeCAD the file is attached with both solids the one with bevel successful and the other without.

Hi pafurijaz, I'll investigate why the fillet is failing here but this type of shape where it's well defined by 2D profile curves would be better to build with the NURBS modeling tools in MoI rather than as a sub-d conversion.

With 2 planar curves as profiles like this:


You can use Boolean intersection to generate this result:


This structure will be easier to fillet:

Hi pafurijaz, I think the issue is that the filleter in the geometry library that MoI uses is not able to build a fillet with this type of edge topology:



The problem is that a fillet segment needs to be constructed between these 2 faces, but they do not share an edge in common, they only share a vertex in common:



This will probably be a limitation in MoI's filleting until I'm able to get a different geometry library set up for handling filleting.

Thanks for the answer, and in part I had guessed that the problem was due to that point, of intersection on the edge, and you are right the best way is to recreate the geometries with Moi3D, but sometimes it is easier like that because I have many objects to convert.
