Is there a list published anywhere of what file type versions can be opened in each Mastercam X releases?
Myself, I would like to know what version SolidWorks parts files can be opened in each version of Mastercam X2, X3, X4, X5 & X6.
Meaning these file versions: SW2009.sldprt & SW2009.sldasm, SW2010.sldprt & SW2010.sldasm, SW2011.sldprt & SW2011.sldasm, SW2012.sldprt & SW2012.sldasm, SW2013.sldprt & SW2013.sldasm.

It seems to be a big mystery. The manual simply says, Mastercam supports these file types: SolidWorks, Pro E, etc...
