Hi Kevin,

I wasn't really thinking of Loft for that particular case, just that when you Loft through some curves the surface that is created will pass through those curves... That's the kind of "make the surface go through here" control that you would need for that kind of exact trim to work, if I understand what you are talking about.

But you probably can't use Loft for the situation that you show there because you'll get weird wiggles if you try to incorporate a loft cross section that is so differently aligned than the others...
