Summary of CAD Area Query Methods
Recently, there have been inquiries regarding methods to query area in CAD, so I’d like to share and discuss three approaches that I have mastered:
1. AA Quick Query Method
Though called “quick,” this method is not necessarily fast; it mainly involves inputting commands. The command AA is straightforward but limited to simple shapes made up of straight lines.
To use it, enter the command AA, then click on the starting point, followed by each subsequent point. Press Enter or Space to finish.
The area will be displayed below the command bar, for example: Area=59802.9627, Perimeter=967.7956.
2. Fill Pattern Query Method
As the name suggests, this method uses pattern filling to calculate the area. It applies to a wide range of shapes, but because of the heavy computation involved, results may not display immediately and could cause the program to crash.
After completing the pattern fill, select the pattern, then enter the command LI and press Enter to open the query dialog box.
3. Multi-Segment Line Query Method
This polyline method is my favorite technique. Using the command PL, draw a complete polyline. Then, use the command LI to query the area. This method is versatile and responds quickly, making it highly recommended.
