How to Find Length of Polyline in AutoCAD?

Understanding Polyline Length in AutoCAD

When dealing with designs in AutoCAD, knowing how to accurately measure the length of polylines is essential for precision and efficiency. Polylines are versatile shapes used in various drawings, and understanding their properties can greatly enhance your workflow.

How to Measure Length of a Polyline

  1. Selecting the Polyline:

    • Open your AutoCAD workspace. Ensure the drawing containing the polyline is active.
    • Click on the polyline you wish to measure. The properties related to that selection will be displayed.
  2. Using the Properties Palette:

    • To view more detailed information, access the Properties palette by typing PROPERTIES in the command line, then press Enter.
    • With the polyline still selected, the Properties palette will show various parameters, including the total length of the polyline.
  3. Using the Measure Tool:

    • Navigate to the Home tab on the top toolbar.
    • In the Utilities panel, find and select the Measure drop-down menu.
    • Choose the ‘Distance’ option to measure the length of a polyline.
    • Click to specify the first point of the polyline, then click to specify the second point. The command line will display the total length measured.
  4. Using Command Line Approach:
    • Type LIST in the command line and press Enter.
    • After that, select the polyline you want to analyze.
    • The command line will provide a detailed breakdown of the polyline’s properties, including its total length.

Setting Width of a Polyline

  1. Enter Polyline Edit Command:

    • Access the command line and type PE (PolyLine Edit), then press Enter.
  2. Select the Polyline:

    • Click on the specific polyline you want to modify.
  3. Adjusting Properties:
    • With the polyline selected, choose the ‘Width’ option from the list of available commands.
    • Enter the desired width measurement when prompted, and press Enter to apply the change.

Finding Length Using Layouts

If you are working with layouts rather than model space, the process is slightly different.

  1. Switch to the Appropriate Layout:

    • Make sure the layout where the polyline is drawn is active.
  2. Activate the Measure Tool:

    • Click on the Home tab. In the Utilities panel, use the Measure drop-down menu and select ‘Distance’.
  3. Measuring in Layout Space:
    • Click on the endpoints of the polyline or select its geometry to get an accurate measurement displayed on your screen.

Frequently Asked Questions

1. Can I measure multiple polylines at once?
Yes, you can use the LIST command to select multiple polylines and obtain a report on their individual lengths as well as total length.

2. What if I need to convert the polyline length to different units?
You can set your drawing units in AutoCAD by adjusting the settings in the Units dialog, accessible via UNITS in the command line. Change the unit type to suit your requirements.

3. Are there any shortcuts to measuring lengths in AutoCAD?
Yes, using shortcuts such as L for Line and PE for Polyline Edit can speed up the measurement process significantly. Familiarizing yourself with these commands can enhance efficiency.
