The file in question can be found here: Air Fan - no base
When I attempt to open this file in Autodesk Inventor Professional 2012 (Student Version), I get an HTML translation report that says Error - Translation failed This version is not supported.
If the file really is from an older version of Solidworks, why won't it open in Inventor 2012? Thanks.
I think Inventor's support for SW files stopped at a certain version of SW, so it doesn't matter which version of IV you have. I might be wrong though.
STEP and IGES files are better anyway.
I have Inventor 2011, and I know that it won't support any Solidworks files. You need to get the drawing uploaded in STEP/IGES format so you can open it. It is a good idea to upload all your drawings in your regular format as well as include a STEP/IGES version of that drawing, that way more of the "GrabCAD Community" can have the pleasure of looking at your drawing.
