Setting limits

In AutoCAD, we make our drawing on a scale of 1:1, which means we are drawing to the actual scale of the project. For example, a square plate of 10 mm by 10 mm will be exactly the size in AutoCAD as well. But the drawing area can make the 10mm by 10mm square very big or small, depending on the zoomed state of the screen. If your drawing is zoomed in, the square may appear bigger and if it's zoomed out, the drawing may appear tiny.

So, depending on the size of the drawing that you want to make in your AutoCAD file, you can set the limits and then these settings can be used wherever needed. In the following example, we will add a drawing limit of 60, 40 units in our drawing:

1. To set the limits, type the LIMITS command and press Enter.
2. 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.

3. 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:

4. 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.
5. The screen will reset to adjust according to the newly specified limits.

In our example, the height of the screen will be 40 and the length of the screen will be 60, or any other that will be proportional as per the screen size. For example, in a square screen, the length will now be 40 as well, but for a rectangular screen, the length will depend on the aspect ratio of the monitor.

Setting the limit will just let you adjust a reference for working on the drawing. This property will not affect your drawings in any way, and you can freely zoom in and out to the change the drawing area and make your drawing even go outside this limit.
