How can I scale my Autocad drawing so when I dimension certain parts it will output the distance in feet? I downloaded the AutoCAD 2010 demo and I'm trying to figure out how to fix my scale. I want my scale to be 1"= 20' but my drawing is in units of inches. How do I get my dimensions to read in feet? I'm a newb to 2010 but the last AutoCAD that I am familiar with is 2006. Any help is much appreciated.
