I recently upgraded to version 4. I now can no longer save any of my work to an STL file. Is this the way it is, or am I missing something? I will have to go back to version 2 if I can not save to STL. Sad, but I just spend approx. 4 hours designing something I need to print on my FDM 3D printer and now I can not save it to the file I need.
