Mirroring a map?

[Memento Mori]

Is there any way to do this? I'm making a simple arena map for practice, and just want both ends to be symetrical (from left to right in the top XY view), however rotating by 180 makes the stuff on RED's side be "south" rather than "north" directly opposite the BLU side, making it not match up. I'd rather not do the same stuff on the other side if this is possible. I'm not sure what box to put 180 in but I've tried all of them to no avail. (using CTRL+M)

thanks in advance

Hit CTRL + L (Flip Horizontally) then CTRL + I (Flip Vertically).

Thanks I knew it was in there somewhere

For an alternate method you could also select all, click the selection once in the 2D View to change to rotate mode, click and drag a corner handle until it's totally flipped 180. Does that same thing though.

Rather than manually rotate it the way Hojo suggested, I would use the Ctrl+M translation/rotation/scaling tool, its just safer because its more exact.

I'd go with TheDarkerSideofYourShadow's advice for this one. I've had problems with light_spot's keeping proper orientation to the world if they're pointing somewhere other then straight down using the "flip" tools, but never with the rotate tools.

Rotate tools do what they say, they rotate the selection, they don't mirror it. While it does pose problems for a few entities that use angles in a weird way (light_spot being the most common instance), you may not have the choice.

You could try a scale transform by -1 on the X (or Y) axis. I doubt it will do anything different from Ctrl-I/L though.
