[QUOTE=valkyr;226935]Something like AutoCAD would probably be just as useful…
anyway, all that talk of drawing maps on paper reminded me of something I saw a while ago… Some guy had written a tool to take drawings and turn them into Quake maps. So you’d draw the outline of the map on paper, with doors and different entities being signified by different colours. Then you’d scan the drawing and the tool he’d written would turn the image into a .map file.[/QUOTE]
lol lol something like autocad, than you get GTKradiant 
try Revit instead, it will replace autocad ove the years too btw
