So I use Inventor at school; of course they use windows based products, but I have a MacBook. I downloaded Inventor off the Mac App Store. I noticed it's lacking in many ways eg. cannot create polygon, cannot loft, etc. Anyways, I was wondering if there was a way that I could have multiple part files open at the same time, like you can on PC. Because whenever I create a new part file it closes the one I was working on, regardless if I saved it or not. It is VERY annoying. So, is there a way that I can have multiple projects open at the same time, and be able to just click and work between my two projects? Any help would be greatly appreciated, thanks.
