Entering Fractional Distances

If you try to enter a distance like 8 5/8” into AutoCAD, it’ll stop as soon as you hit the spacebar. Instead, type 8-5/8”. You don’t need the inch mark, but it won’t hurt anything. To enter a distance with feet and fraction inches, like 3’-7 3/8”, use this format: 3’-7-3/8”. Again, you don’t need the first dash, or the inch mark (3’7-3/8 will work just as well for two fewer key strokes), but they won’t cause problems either.
