Fillet don't works in one pass but yes one by one! :)

For help the "Inset" Function on objects that have been Splited by Max's "SPlit".
Just export the object, delete it, and re-import it! Make the Inset by 2 faces!

Be careful, the object cannot be subdivided directly!
It will be necessary to export it in OBJ, option "Quad + Triangles"
then use the _importOBJ by Max or the native function!
SubD / Create / From file!

Very theoretical but ultra powerful! The ISect boolean!



But don't forget also the Boolean Merge ! ;)

Flow for make a sort of "cutting" volumes on curvated surface!
The more versatile function of Moi! ;)



More cool than LineWeb + Sweep... ;)
