[Smtk-developers] Loading in STP Models

[Robert Michael O'Bara]

Hi All,

I think I can show we are no getting the correct topology - Load in Engine-block.igs and you can see we are getting a lot of volumetric bodies which are not volumes (they could be sheet bodies but they definitely not volumetric - this is one of the “volumes”.
