I like my maps to be symmetrical, and I wanted to know since a casual poking around didn't find anything: Are there any commands or tools in the Starcraft 2 Galaxy editor to assist with making my maps symmetrical? Even an ability to export the heightmap for editing would work.

  • Highlight the terrain, copy and paste it, but don't place the copied terrain yet.

  • Under the Edit menu, use the Flip and Rotate options to get it symmetric.

I can't seem to find the tool that highlights terrain >.< – RCIX Nov 18 '10 at 23:42
Ok, figured it out! Use Selection Mode (space, or Tools > Selection Mode) with Use Group Selection on. Thanks :) – RCIX Nov 19 '10 at 0:44


Map -> Symmetry

if you set it up before drawing on your map, all your changes to the terrain, decorations, units (e.g. minerals) will be automatically replicated on your map.
