Mastercam X4 - stl stock problem

Hello Forum,

I have a problem importing a stock (.stl) into Mastercam X4 created by Solidworks 2012 X64. The stock imports above the parasolid model. The coordinate systems, both created in Solidworks dont even line up. The orientation is correct, but thats all. I did not have this problem using Solidworks 2010 x32. Anybody else experience this or have any ideas?

Thanks in advance,

Wayja
