I am currently working with a Student/Education version of Maya 2012 on a Windows 7 system. I loaded the plug-ins for Direct Connect and attempted to export a Maya ".mb" file as a ".stl" file. However, when I go to open the exported file I realize no data has converted with the file. Can anyone inform me if there are issues translating Maya files to an STL format?
You may try also posting in the Area as well. I did find this older post here for Maya 2009.
