I have to comment that the videos on the surface modeling, deform, fill
and loft as well as mold tools are very generalized!
Hopefully unsuspecting users/buyers don't believe that those examples
give any real understanding of modeling with surfaces or creating molds?
For instance, they mention that continuity conditions on boundaries are
controllable, that is totally dependent on adjacent surfaces or edges
(if you use 3dsketches or composite curves) of the boundaries.
BTW, the graphics preview is not always available and also does not mean
your surface will resolve.
If you are a prospective buyer or you're considering SW, ask the sales
person this question.
Are surface fills, lofts, sweeps and deform surfaces consistent per
release or sp!?
Answer = NO!
