Fast way to create a command map, is to load the map in ET with devmap,
speed is your movespeed, cg_fov 1 would make it perfect as a map, but probably the map will be to big.
Now move out .. very far, and watch straight down. Then take a screenshot, first clear hud and all,
take the screenshot
Now close ET, and fit the screenshot into the tracemap...
This seems to be useless for mapscripting, at least I couldn't make an existing model of the map to be visible; I suppose has to be set at compile time.
Load etpro, load the map with devmap, or force somehow sv_cheats to be enabled.
Use /debugmap or /mapdebug to enable/disable debug mode. You can then shoot at any surface, and the game will tell its origin and more infos.
thats all, and you will see the AABB of the fakemodel.
