Hello I am using MOI to translate Solidworks 2008 and 2010 files into quad geometry for rendering in Modo.

Hi skateboardkid, I received the file and replied to you in PM - it looks like it may be some kind of bug in reading IGES entity 186. I'll need to ask the guy that makes the IGES translators that I use about it.

You can probably avoid it if you change your export settings in SolidWorks to use individual surfaces (which is somewhat more common for IGES), which would be something like entity type 144 or type 143, rather than entity 186.
