OK, I pulled the trigger and upgraded to SC8. On the whole, I'm pleased. Graphics are sharper, and simulations calculate faster.

One problem, though. The add-in for Autodesk Inventor appears to be broken. Trying to import an Inventor model (.ipt) produces an "Import Error: Invalid File Extension" message. It's easy enough to work around by translating the model into IGES, but I'm wondering if anyone has a simple fix.

TIA.
