How to Calculate Area in AutoCAD 2007

Understanding Area Calculation in AutoCAD 2025

Calculating area in AutoCAD can be essential for a variety of design and drafting tasks. Here’s a comprehensive guide on how to calculate the area of both regular and irregular shapes specifically in AutoCAD 2025.

Steps to Calculate Area in AutoCAD 2025

1. Starting the Area Command:

   • Open AutoCAD 2025.
   • Navigate to the command line at the bottom of the interface and type AREA, then press Enter. This initiates the area measurement tool.

2. Selecting Objects:

   • When prompted, choose the option to select an object if you’re measuring a predefined shape (like a circle or rectangle).
   • Click on the geometry whose area you want to calculate. The system will display the area immediately in the command line, along with its perimeter.

3. Measuring a Closed Polyline:

   • If the shape is a closed polyline, you can follow the same steps as above. Ensure to close the polyline entirely to get an accurate area measurement.

4. Manual Area Calculation for Irregular Shapes:

   • For irregular shapes, the process requires a few more steps:
     1. Break the irregular shape into recognizable components (e.g., triangles, rectangles).
     2. Use the AREA command for each component individually.
     3. Sum up the areas of these components to get the total area.

Using Object Properties for Area Display

1. Displaying Area in Square Metres:
   • If you need the area specifically in square metres, first create a Multiline Text (MTEXT) box.
   • Type “Area: ” as a prefix and right-click in the text box to select “Insert Field.”
   • Choose “Object” from the Field Names box, then opt for “Area” in the Object Type section.
   • Select the object for which you’re measuring the area, and the calculated area will display in the MTEXT box.

Understanding Area Formulas

Familiarity with area formulas can enhance your ability to estimate areas quickly:

• Rectangle: A = Length × Width
• Square: A = Side²
• Triangle: A = 0.5 × Base × Height
• Circle: A = π × Radius²

Measuring Coverage Area

To measure the coverage of a specific shape (e.g., for tiling or landscaping):

1. Calculate Height and Width:
   • For rectangles or squares, multiply height and width to find the area.
   • Ensure the measurements are consistent (all in meters or all in centimeters).

FAQs

1. How can I find the area of multiple objects at once in AutoCAD?

You can select multiple objects while using the AREA command. Simply drag a selection box around the objects you wish to measure, and AutoCAD will provide the total area for all selected items.

2. Is there a way to calculate the area of a curve in AutoCAD?

Yes, curves can also be measured using the AREA command, provided they are closed. Ensure the curve creates a full perimeter for an accurate area reading.

3. Can AutoCAD display the area in units other than square metres?

AutoCAD can display area in various units based on the drawing settings. You can set your units in the drawing properties dialog, and the AREA command will adhere to this setting when displaying results.
