TAD works with 2 User Interfaces. The Ribbon Menu system has 10 “tabs” and you can switch easily from one to the other. Each has its own set of functions associated with that tab. But we've also given common functions available from practically several tabs, so that you don't have to switch in the middle of some work that you doing from one tab.

If you go to the Help ribbon, you can Toggle TAD to the regular menu and toolbar based user interface. TAD remembers the last UI you had used, and would open up using the same UI you had used last time.

NOTE: Switching of the UI can only be done when no TAD models have been opened.
