Each base is inside a wall that I need to make ramps for. I go to doodads and then compound doodads and there are ramps. They only work in 2 of the 4 corners, and I need to rotate them to work in the other corners.. how do I do this?
None.
NudeRaider -- blessed innocent soul knows nothing of the strife we had before EUDs were discovered 
DarkenedFantasies -- Probably just didn't care. For example, at some point before release, they've updated the graphics of some of the Protoss buildings (Forge, CyberCore, Citadel, Observatory, Arbiter Tribunal), but instead of properly re-rendering them with edited 3D models, they did crappy copy-paste jobs on the rendered graphics.
