This is an interesting discussion and I want share my experience in this field, I made a few experiment and I understood how modelling suddiv for nurbs conversion with moi3d.
Project a curve to a complex volume (yet well working for subdive)
Trim
Kill Curve(s)
Join
that all! :)
PS Extrude can't work because face(s) are not in middle of surfaces!
So Copy Move one face(s) then "Bridge" one to one ! Copy / Move Faces can be Multiple!
Flow function can be practical for SUbDIve!
Here a cube was projected on a Sphere...of course as always imagination must be large for predict the result!
Searching something for all kill the internal volume (faces, edges) for make some cool subdivided object...
it appears that is very difficult directly in Moi ! (for the moment (?) )...
Boolean union will remove the internal faces but also merge together some of the outer ones.
Edit Join don't remove internal faces!
So no success!
But i have found some little tricks! :)
- Export as OBJ / Ngon Without Without Weld vertices along Edges!
- Import OBJ from SUbDiv/ Create /From File
- Boolean Union
- Max Subdiv
That works fine...except for this case!
don't works when "cubes" are tangent by a commune vertical edges!
Works in other compact or alone positions!
the bad case (works in other cases! )
so no total success again!...
but i have found another trick for this particular case! :)
Up or down the top face of one of these 2 boxes by a very, very tiny distance!
et voilà! :)
Have fun subD modeling before a script or command OR NODES who kill all internal volume! :)
