I'm making a map with Starcraft 2 air crafts but I don't want to build the ship wrong and restart. So is there some map maker that I can make on the computer for sandbox and then use that to make my map on halo 3? That would be useful. I've got pictures of the ships but when I make the ships I don't want to make the ships look crappy looking.
Download google sketchup and a sandbox template and then you can design all your maps to finest detail before you start to forge.
