How to Calculate Perimeter in AutoCAD 2017

Understanding Perimeter Calculation in AutoCAD 2025

Calculating perimeter in AutoCAD can be accomplished effectively using a few tools available within the software. The following sections will detail different methods to find the perimeter of various objects in AutoCAD 2025.

Method 1: Using Polylines and Regions

1. Create Your Object: Start by drawing your object using polylines. If you already have a closed shape, you can proceed to the next step.

2. Explode the Polyline: If your polyline consists of multiple segments, you’ll want to combine these into a single region. Select the polyline, then use the “Explode” command. This breaks down your polyline into manageable sections.

3. Convert to Region: Type the command REGION in the command line. Select the exploded polyline to convert it into a region, enabling you to analyze its properties.

4. Access Mass Properties: Navigate to the menu and select Tools > Inquiry > Mass Properties. A dialog box will appear detailing various attributes of the region, including its perimeter.

Method 2: Using the AREA Command

1. Activate the Command: Type AREA into the command line and press Enter. This command helps you determine both the area and the perimeter of the selected object.

2. Select Object: When prompted, choose the closed boundary of your object (such as a rectangle or circle). Make sure your selection is accurate for precise calculations.

3. View Results: After making your selection, AutoCAD will display the area and perimeter information in the command line, providing instant calculations without needing additional steps.

Method 3: Command Line Inquiry

1. Utilize the LIST Command: For quick access to properties, you can use the LIST command. Type LIST in the command line and select your object. This will output various details, including the perimeter, directly in the command line.

2. Properties Palette Access: Another method is to use the PROPERTIES command by pressing CTRL + 1 to open the Properties palette. Here, you can see detailed dimensions, including the perimeter, listed in the Geometry section.

Method 4: Measure Tool in AutoCAD

1. Select the Measure Tool: Go to the Home tab, click on the Utilities panel, and select the Measure drop-down menu. Choose the Distance option.

2. Specify Points: Identify the starting and ending points of the lines to measure. For accurate measurements, make use of object snaps (osnaps) for precise selection.

3. Calculate Length: The distance between your specified points will be displayed in the command line. Repeat this process for all sides of the shape to summarize the full perimeter.

Frequently Asked Questions

1. Can I calculate the perimeter of an irregular shape in AutoCAD?
Yes, you can calculate the perimeter of irregular shapes by using the ways described above. Make sure the shape is closed, and you can use the AREA command or the LIST command to get the perimeter information.

2. Is there a shortcut for accessing mass properties in AutoCAD?
The mass properties can typically be accessed quickly through the command line. Use the command MASSPROP directly to open the mass properties tool without navigating through menus.

3. Are there any tools in AutoCAD specifically for measuring irregular areas?
AutoCAD provides several measurement tools, including the AREA command, which can be applied to any closed shape to derive its area and perimeter effectively.
