If I use SUPro 8 at school, and I need to work on the project at home using SUPro 2016; Will it work? Then after, Could I return back to SUPro 8 and everything would work?
It will work. The only thing you have to do is remember to save the files as SU 8 when working on them in SU 2016.
Ok, Thanks! - I’ll also tell my teacher that, so that he can let people know they can finish their projects too on SU2016. Also, Would Sketchup Make work?
Yes, Make will work. There is no difference between the file formats for Make and Pro.
