How do you use import subd option in MoI.

Firstly I`ve thought that technology is implemented to import some meshes, convert them to nurbs and do some booleans and fillets on it. Booleans works for me but fillets almost always doesn`t.
Michael told be on different thread that fillets are complicated with calculate and it works only on clean curves and surfaces.

1) Is there some trick to clean a messy curves and surfaces generated after obj>subd conversion to nurbs?

2) How do you use your subd meshes after import? Do you use it only as bakcground reference to build new cleaner curves and surfaces inside MoI? I have strange feeling that I use it in wrong way and I have to optimistic vision of that conversion :)

I hope that some day it will be so easy like: take some subd meshes, convert to subd and then to nurbs and after it you may use all commands without worry about topology becouse you chave clean solid :) I know it`s sci-fi wish :)

I`ve tried also fillets in Rhino 6 and surfaces also exploded in similar way (quite low subd mesh with additional loops on hard edges). I`ve heard that Rhino 7 will have more commands to support SubD modelng. I`m curious if subd meshes created in Rhino 7 will also explode after boolean substraction and adding fillets over it same way as imported ones. If yes then whole point of merge subd modeling and nurbs is not so seamless as I thought before.

I love subd creation of surfaces but I hate blending them and I hate to make fillets on complicated shapes. I love nurbs precision, blends, nurbs booleans and fillets and I don`t like creating organic shapes in them. I wish that both worlds will be mixed seamlessly someday.

Cheers!!!
