Hi Michael,

apologize, if I have to bother you again!

Tried my second vehicle for Mini-Production.
This time I cannot export the object as IGS.

Maybe because I cannot get it to be a "solid"

I think MOI urgently need something like an "Optimize"-Command.

Even with "Object-Snapping" enabled and really paying attention when
drawing curves and making "network-faces", I very often notice, that,
when zooming very close, that corners/edges of the faces do not match and
have small gaps.

What can I do in such situations?
How do I get a "sold" Object?

thanks Mike
