How Do You Find the Area of an Irregular Shape in AutoCAD?

by

An irregular shape in AutoCAD refers to any shape that does not have standard geometric properties, such as a circle or a rectangle. Finding the area of an irregular shape can be a challenging task, but with the right tools and techniques, it can be easily accomplished.

Using the AREA Command

AutoCAD provides a powerful command called AREA that allows you to calculate the area of any closed shape, including irregular ones. To use this command:

  1. Select the closed shape by clicking on its boundary.

  2. Type AREA in the command line and press Enter.

  3. The area of the selected shape will be displayed in the command line.

Note: The AREA command works only for closed shapes. If your irregular shape is open or has gaps, you need to ensure that it is closed before using this command. You can use the PEDIT command to join any open ends and create a closed boundary.

Calculating Area Manually

If you prefer a more manual approach or want to understand how AutoCAD calculates the area, you can break down your irregular shape into smaller regular shapes and sum up their individual areas.

Here’s how:

  1. Divide your irregular shape into smaller, more manageable sections using lines or other geometric shapes that are easier to calculate.

  2. Calculate the area of each section using standard formulas. For example, if you have divided your irregular shape into triangles and rectangles, use their respective formulas:

  • A = (base * height) / 2 for triangles
  • A = length * width for rectangles

Note: Make sure to use consistent units of measurement throughout your calculations.

  1. Add up the areas of all the sections to obtain the total area of your irregular shape.

Using Third-Party Plugins

If you frequently work with irregular shapes and need more advanced tools for area calculations, you can explore third-party plugins available for AutoCAD. These plugins offer specialized features and algorithms that can accurately calculate the area of complex irregular shapes.

Note: Before installing any third-party plugin, make sure it is compatible with your version of AutoCAD and comes from a trusted source.

In conclusion,

Finding the area of an irregular shape in AutoCAD can be achieved using various methods. The built-in AREA command provides a quick and easy solution for closed shapes, while manual calculations allow for a deeper understanding of how the area is determined.

Additionally, third-party plugins offer advanced capabilities for complex irregular shapes. Choose the method that best suits your needs and get ready to conquer any irregular shape calculation!
