I recently changed to 2012 SP2 from 2011.  I am finding that sometimes when I import a STEP file (from a vendor web site) when I go to save the resulting .sldprt I get a "unknown error has occurred" error. It does not matter where I try to save it.  The workaround I found was to export the .sldprt file to a step, import that step  and then I am fine.  Anybody else run into this?  It may be specific to this one vendor but the file does  import  to a valid solid.

Thanks

John

I can't up load the STEP file but here is the vendor page:
