User reviews

Cannot enter any data

Start up the app, and all I get is the drawing display. I cannot enter any information. It just ignores me if I tap one of the tabs at the bottom of the screen. According to the App Store, it is supposed to work on this iPad.

It does bring up the sample truss. But I cannot get the Nodes, Members, etc., displays to come up with that truss either.
