How to Get the Total Length of Polyline in AutoCAD?

Overview of Polyline Length Measurement in AutoCAD

Understanding how to effectively measure the total length of a polyline in AutoCAD can significantly enhance your drafting efficiency. Polylines are essential elements in AutoCAD, representing connected lines and curves that define shapes and paths. The following instructions will guide you through the steps to obtain the total length of a polyline in AutoCAD 2025.

Using the List Command to Find Polyline Length

  1. Access the Command Line: Open your drawing in AutoCAD 2025 and ensure that the command line is visible at the bottom of the workspace.

  2. Initiate the ‘List’ Command: Type LIST into the command line and press the Enter key. This command allows you to retrieve specific information about selected objects.

  3. Select the Polyline: Click on the polyline whose length you wish to measure. After selecting, press Enter again.

  4. Review the Information: A dialog box will appear containing various details about the selected polyline. Look for the entry labeled "Length," which provides the total length of the polyline accurately.

Measuring Length from the Command Line

  1. Select the Right Layer: Navigate to the layer that contains the polyline. Ensure you are working on the correct layer where you intend to measure the length of objects.

  2. Click on the Polyline: Select the polyline directly. Once selected, you will notice the length displayed in the command line, as well as in a dialog box that may pop up, providing additional context, such as layer name and total length.

  3. Review the Command Line Output: The command line provides instant feedback, making it easy to identify the length of the polyline without any extra clicks or commands.

Summing Multiple Polylines

  1. Access the Modify Tools: In the Home tab, locate the Modify panel and click on the "Edit Polyline" option.

  2. Select the First Polyline: Choose a polyline, spline, line, or arc that you wish to edit.

  3. Join Command: Type J for Join and press Enter. This command allows you to combine several line segments into a single polyline.

  4. Select Additional Segments: Click on additional polylines or lines that are connected end-to-end. Make sure the endpoints are aligned to ensure they combine correctly.

  5. Finish the Command: Press Enter to complete the join operation. The new combined polyline will now reflect the sum of the lengths of the individual segments.

Visual Measurement of a Polyline

  1. Zoom to the Area: Adjust the zoom level so you can clearly see the polyline you want to measure.

  2. Start the Measurement: Access the measurement tools and select the starting point of your polyline.

  3. Click Along the Path: As you continue clicking on subsequent points defining the polyline, AutoCAD will automatically calculate the total length.

  4. Complete the Measurement: To finalize the measurement, double-click, which will conclude your polyline path.

Frequently Asked Questions

1. Can I measure polyline lengths in units other than feet or meters?
Yes, AutoCAD allows you to set the units in which you want measurements displayed. You can configure the drawing units to your preferred format in the settings.

2. What if I cannot see the length measurement in the command line?
Ensure that your command line is activated and visible. It’s possible that the length is being calculated but not displayed due to settings or visibility options. Check if your layer is set correctly for visibility.

3. Is there a shortcut command for quickly measuring length?
Yes, using the DIST command allows you to quickly measure distances between two points, and you can use it to measure segments of a polyline manually if needed.
