AutoCad 2010 Commands

 Working

1) https://subscription.packtpub.com/book/business-&-other/9781789809152/1/ch01lvl1sec05/setting-units-and-limits

To set the limits, type the LIMITS command and press Enter.

The command line will now prompt you to specify the lower-left corner of the screen from where you want the limit to start. By default, 0,0, or the origin, is selected. You can specify any other point as well if you want, then press Enter.

Now, the command line will prompt you to specify the upper-right corner of the screen for the limit. Type the coordinates of the point in the form of x, y and press Enter:

Select 0,0 as the lower-left corner and 60,40 as the upper-right corner. After setting the limits, type Z and press Enter, then type A and press Enter again in the command line.

The screen will reset to adjust according to the newly specified limits.
