When I upload my model it does not stay in the Home view orientation like it is in my Inventor model.
just "save as" it in .stp or .igs format.
You have to use the export option for step
did you try .igs ? every software allows you to save as .step (or) .stp format
if not there might be installation problem.
Didn't appear to change anything, I did a "Save Copy As" which offered the STEP option. The "SAVE AS" option did not offer STEP option.
