Another Workflow! :)
Rocket 3F (OBJ)-->Fusion 360 Tsplines (IGES)---> Moi (3DM) = Nurbs
(i know that is a direct bridge Rocket --> Moi : it was for see what happend inside Fusion! :)
Artifacts' lines on the top round is just due to the bad angle position of the view!


Rendering Fusion 360 till Moi has one! ;)
(absolutly not any regulates anywhere)
