Hi Michael,

all told problems occured in this second 3dm-file I have attached.

Good tip btw with Modo and Inventor.
I always thought, that Polymodels could not be converted into nurbs. Only vise versa.

But anyway. MOI is a plessure to work with because of its simple UI and workflow
(except the problems I'm still running into)

So I'm trying to get better skills with nurbs modelling.

Therefore: If I already have the main body of the car (like in my file) how do I make the bottom of the car as
one surface so it fits exactly to the wheel arches?


thanks
Mike
