How Do I Calculate the Area of a Polyline in AutoCAD?

If you are working with AutoCAD and need to calculate the area of a polyline, you’ve come to the right place. In this tutorial, we will walk you through the steps to accurately determine the area of a polyline in AutoCAD.

Step 1: Select the Polyline

The first step is to select the polyline for which you want to calculate the area. To do this, use the POLYLINE command or simply click on an existing polyline in your drawing.

Once selected, it will be highlighted.

Step 2: Use the AREA Command

With the polyline selected, type AREA in the command line or access it from the ribbon by going to Modify > Properties > Area. Press enter or click on the command when it appears in the command line.

Option 1: Automatic Calculation

By default, AutoCAD will automatically display and calculate the area of your selected polyline as soon as you enter the AREA command. The calculated area will be displayed in square units (e.g., square inches or square meters) depending on your drawing settings.

Option 2: Select Objects Manually

If you have multiple polylines or closed shapes overlapping each other, AutoCAD may not be able to accurately determine which shape’s area you want to calculate. In such cases, you can manually select objects by typing O (for Object) and pressing enter.

Then click on each individual shape to calculate its area separately.

Additional Tips

  • If you want to calculate the area of multiple polylines at once, you can select them all before using the AREA command. AutoCAD will display and sum up the areas of all selected polylines.
  • Remember that the AREA command only works for closed polylines or shapes. If you try to calculate the area of an open polyline or a line segment, AutoCAD will give an error message.

  • If your polyline has holes or voids within it, AutoCAD will include their areas in the calculation by default. If you don’t want these areas to be included, you can use the HATCHEDIT command to remove them before calculating the area.

Now that you know how to calculate the area of a polyline in AutoCAD, you can easily determine the size of various shapes within your drawings. This knowledge is particularly useful for architects, engineers, and designers who need accurate measurements for construction projects or design plans.

Remember to save your work regularly and practice using these commands on different polylines to become proficient in calculating areas in AutoCAD. Happy designing!
