this app is a pain in the butt. I have to save after every individual addition because it crashes constantly.

It's tough to work with when it works. But mostly it doesn't work. It crashes frequently and if it works it's like 1990's software.

Something wrong with this app, when i try to open immediate close the app.I have a Mac Mini 2010 8gb memory and 2.5 of processor with Sierra. Quick3DPlan DS. Obviously i given 1 star because i can see anything at all of this software.

what else to say. other than I am glad I did not purchase and only had a one month subscription.
