Hello Bruno,

<<<In order not to do this model for the 12 time hahahah, I mean before proceeding to use that technique. Do you think by making the cube with different continuity on the radius I will solve it just doing sweeps (intersection as rials and two curves as profiles).>>>



It's only one way - but in my opinion you don't Need more than one Profile.

Have a nice day
Karsten
