why surfaces?
(OP)
I apoligize if this is a silly question, but I hear so much about using surfaces to design aesthetically pleasing products and I am a little confused as to why. How is it possible to design a surface that cannot be defined as the just the boundary of a ordinarry solid.
Thank you for your responses

RE: why surfaces?
The problem with working in solid modeling all of the time is the fact that there are a series of "rules" that the model has to conform to so that Pro/E can derive the model's mass properties & such.
Since surfaces have zero thickenss, the rules which Pro/E uses to define them are a lot more forgiving. So you can achieve certain geometry in Pro/E with surfaces that would technically be impossible (or just impractical) to do using solids.
Another benefit to using surfaces is the time it takes to regenerate them. Since Pro/E does not have to update the model's mass properties after a surface feature, it takes a lot less time for a model to regenerate when compared to solid-only models. The best practice in this case is to define as much as possible in surfaces, Solidify these surfaces towards the end of the regeneration sequence, and then add any other solid features (screw bosses, holes, ribs, cuts, etc.) as needed.
Hope this helped
