Well for rotating you can set it either by triggers or by Object editor, or even Terrain editor which can rotate units by pressing hotkeys
First of all, make sure you click space so you can select units, and press any hotkey from 0 - 9 , and try without that 'Numpad On' light on, just turn it off so , 'Del , Fin , pg up , pg down' work , they have benefit too
If it's a building you should default facing in Object editor, it can be easily found
Third, GUI editor gives u this trigger, use it :
-
Unit - Make Unit face 'Your angle'
I wish this helps
