AutoCad Basic Command ll How Set limits 2d Commnad in AutoCAD. 

In AutoCAD, the `LIMITS` command sets and controls the drawing boundaries. This helps to define the working area of the drawing. Here’s how to use the `LIMITS` command:
1. *Type `LIMITS` in the command line and press Enter.*
2. *Specify the lower left corner of the limits.* By default, it's usually `0,0`. You can enter different coordinates if needed.
3. *Specify the upper right corner of the limits.* Enter the desired upper right corner coordinates.
To turn the limits checking on or off, you can use the `LIMITS` command followed by `ON` or `OFF`.
Additionally, you can use the `GRID` command to display a grid that reflects these limits, helping you visualize the working area.
