So...I've been modeling with SolidWorks since 2007. I can't believe that I do not know this one. What is the definition of a face and a surface. It seems that they are a bit similar. I am asking because there are two different constructs in the API. IFace2 and ISurface. If they were not two different things they would not have different interfaces.


Soooo...what's the actual definitions?
