AutoCAD 2010 helps you design nearly anything you can think of, but you do have to recognize some limits. The following table shows limits for drawing scales from 1/16 of an inch to 3 inches to a foot:

Drawing Scale 8-1/2" x 11" 11" x 17" 24" x 36" 30" x 42" 36" x 48"
1/16" = 1'–0" 136' x 176' 176' x 272' 384' x 576' 480' x 672' 576' x 768'
1/8" = 1'–0" 68' x 88' 88' x 136' 192' x 288' 240' x 336' 288' x 384'
1/4" = 1'–0" 34' x 44' 44' x 68' 96' x 144' 120' x 168' 144' x 192'
1/2" = 1'–0" 17' x 22' 22' x 34' 48' x 72' 60' x 84' 72' x 96'
3/4" = 1'–0" 11'–4" x 14'–8" 14'–8" x 22'–8" 32' x 48' 40' x 56' 48' x 64'
1" = 1'–0" 8'–6" x 11' 11' x 17' 24' x 36' 30' x 42' 36' x 48'
1-1/2" = 1'–0" 5'–8" x 7'–4" 7'–4" x 11'–4" 16' x 24' 20' x 28' 24' x 32'
3" = 1'–0" 2'–10" x 3'–8" 3'–8" x 5'–8" 8' x 12' 10' x 14' 12' x 16'
