The triangle count utility is a SolidWorks macro provided by AMD to tell how many triangles your data set own.
This number will help you to find the right card and the right amount of memory your card need to have the best performance.
This utility support SolidWorks 2009 and SolidWorks 2010


caveat: 
  Solidworks 2010 introduced a new format:light weight format.
  If your data are opened in that mode, the triangles count macro doesn't work.
  You have two ways to solve that issue :
  Tools/Options/Performance/uncheck: Automatically load components lightweight allows to solve that if set at start.
  Or right click at the top of the tree and select Set lightweight to resolve.
