Drawing Limits in AutoCAD
The drawing limits are there for a reason. When you start a new drawing, then decide how much space do I need for my drawing. Think of it as the size of your drawing area. Then you can define drawing limits correctly. Type LIMITS enter. Type 0, 0 as lower left corner then type or click the coordinate for upper right corner.
Furthermore, the drawing limits defines the extent of ZOOM all. Tip: You can make a little space around the drawing frame, if you define drawing limits a inch outside the drawing frame. This makes it easier to do PLOT "window".
