How to Use Total Length in AutoCAD?

Understanding Total Length in AutoCAD

The concept of total length in AutoCAD pertains to the cumulative measure of various geometric entities like lines, polylines, and arcs within your drawing. Utilizing this feature effectively can assist in precise planning and execution of designs. Below is a guide on how to use total length features in AutoCAD 2025.

How to Set the Total Length Automatically

AutoCAD offers a built-in feature called the Field function to monitor the total length of selected objects dynamically.

1. Open your AutoCAD drawing.
2. Navigate to the “Insert” tab in the ribbon.
3. Select “Field” from the dropdown options.
4. In the Field dialog, choose “Object” under Field Category.
5. Click on the “Object Type” and select “Length.”
6. Pick the objects whose lengths you wish to sum; AutoCAD will add their lengths automatically.
7. This total will adjust dynamically as any geometry changes are made to the selected objects.

Calculating Total Length Using QuickCalc

For a quick measurement of various distances in your drawing, use AutoCAD’s QuickCalc tool.

1. Initiate the QuickCalc tool by pressing Ctrl + 8.
2. Use your mouse to click on desired points in the drawing to obtain measured distances.
3. As you select multiple points, QuickCalc will display the total length of the measured distances immediately.
4. Once finished, simply close the QuickCalc tool and retain your calculated lengths.

Measuring Polylines for Total Length

To measure the total length of polylines, follow these steps:

1. Access the “Home” tab from the ribbon.
2. Locate the “Modify” panel and select “Edit Polyline.”
3. Choose the polyline you wish to measure.
4. Type J to join segments, should any be separate.
5. Select the additional segments that are aligned end to end.
6. Press Enter to conclude the action.
7. The total length will be available in the properties window after the segments are joined.

Finding Lengths of Lines and Multiple Entities

To find the length of individual lines or multiple lines, various methods can be employed:

For Single Line:

1. Use the command line and type LENGTHEN while selecting the line in question.
2. The command line will display the current length of the selected line.

For Multiple Lines:

1. Utilize the properties palette by selecting multiple lines and checking the total length displayed.
2. Alternatively, you can employ the LIST command by selecting the objects; it will show a detailed report of all dimensions including length.

Troubleshooting Length Display Issues

If lengths are not displaying as expected, consider the following:

1. Ensure that the relevant layers are turned on; dimensions may not appear if their layer is off.
2. Check the text style used for dimensioning; if it’s too small, it will not be readable at your current scale.
3. Confirm that all necessary annotations and settings in the dimension style manager are correctly configured.

FAQ

1. How can I find the total length of a complex shape in AutoCAD?

You can use the LIST command or the Properties palette after selecting the shape to view its total length. Joining segments simplifies this process.

2. Is there a way to automate length calculations for repetitive tasks in AutoCAD?

Yes, consider using AutoLISP routines that can be programmed to calculate lengths automatically based on your specific needs.

3. Can I use total length features in AutoCAD LT?

AutoCAD LT supports many of the same length measurement capabilities, though some advanced features like custom scripting may not be available.
