I'm seeing some very odd behavior with exporting files in solidworks.  Basically it's all about the sequence of the export.  If I perform parasolid export prior to exporting a step, sat, iges... the step, sat, iges formats have missing parts.  The only way to get the correct export is to reopen the assembly file and export the step, sat, iges only.  Why would this be happening?  Is their a export file buffer corruption here?
