The Perimeter command in AutoCAD is a useful tool that allows you to calculate the perimeter of an object or a selection of objects. This can be particularly helpful when working with complex shapes or when you need to determine the length of multiple lines.

**Using the Perimeter Command:**

To use the Perimeter command, follow these steps:

__Step 1:__ Open AutoCAD and create or open a drawing that contains the objects for which you want to calculate the perimeter.

__Step 2:__ Select the objects for which you want to calculate the perimeter. You can do this by using any of the selection methods available in AutoCAD, such as using a window selection, crossing selection, or individual object selection.

__Step 3:__ Once you have selected the objects, type “PE” on the command line and press Enter. Alternatively, you can access the Perimeter command from the Home tab in the Modify panel.

__Note:__If you have not selected any objects before typing “PE”, AutoCAD will prompt you to select objects first.

### The Result:

Once you have executed the Perimeter command, AutoCAD will display a text message on the command line stating the calculated perimeter value. The value will depend on your drawing units settings.

**Tips and Tricks:**

– You can use object snaps while selecting objects for calculating their perimeter. This allows for precise measurement even if there are gaps between lines or polylines.

– If you need to calculate the perimeter of multiple objects at once, select them all before executing the Perimeter command. – The Perimeter command works with various types of objects in AutoCAD, including lines, arcs, circles, polygons, and more. – You can also use this command to measure distances between two points by selecting a single line segment.

### In Conclusion:

The Perimeter command in AutoCAD is a powerful tool for calculating the perimeter of objects in your drawings. By following a few simple steps, you can quickly obtain accurate measurements and save time in your drafting or design projects.

Remember to use the Perimeter command whenever you need to determine the length of lines or boundaries of shapes. Its versatility and ease of use make it an essential tool for any AutoCAD user.
