If thats allowed
Can one rotate the cam in CnC3?

I think most 3D RTS games allow you to rotate the camera.

The screen shot from Age of empires is really fantastic. But, are all those buildings expandable "units"? Is there any specific building in there that could be studied in detail? The screen shot from 'Command and Conquer' shows a couple of buildings that look like bunkers / sheds. The third one, i don't know which game it is from, seems like a military outpost. So, what i understand is, the RTS buildings could be anythng that could be deployed, built and expanded by the player.
So, the model can be shown from above just like how the player sees in the game.

The AoE screen shows buildings that don't actually do anything, but they could conceivably be player-made (some RTS games allow you to build normal houses that increase the total number of units you can deploy, for example), so if you were to do something like that I figure it would be fair game. I've never played CnC3 (or any other one) but those are definitely player-made buildings, so that's why I included it (Off topic: I have to say the CnC buildings don't seem to read very well. I can't tell what the heck those buildings do just by looking at them, except that the second from the left probably assembles something). The last screen is from Company of Heroes, showing worker units constructing a Barracks to deploy basic fighting units from.

So I guess what you could say is that almost any building you can think of could conceivably be used in an RTS, but most interesting would be a building that serves a direct purpose: the construction or training of units, or the refinement or creation of resources.

tl;dr: Yes, RTS buildings can be any buildings that can be deployed, built and expanded by the player.
