AutoCAD 2011’s Drawing Scale and Limits Charts: Millimeters

It’s not a bad idea to set limits for your AutoCAD drawing. The limits represent the rectangular working area that you’ll draw in, which usually corresponds to the paper size. Setting AutoCAD's limits correctly lets you display the drawing grid over your working area, use ZOOM All to display that working area, and plot your working area from model space. The following table sets out the dimensions in millimeters of work areas for different paper sizes at different drawing scales.
