I requested a CAD file from our vendor and he said that they have been sending out STL files because they seem to translate to everyone's different CAD systems.  Ok, I'll give it a try.  I got a file with over 500 surfaces in it.  Impressive, but it is way more than I want to dump into an assembly.  It is also a systems hog, it spins so slowly.

Is there a way that I can simplify this file?

Is there a better format to import than STL?

Thanks for the help.
