AutoCAD Drawing Computation 2D Graphics Area Tutorial

Many people who use AutoCAD for the first time don't know how AutoCAD calculates the area of ​​2D graphics. Today Xiaobian teaches you how to control how AutoCAD calculates the area of ​​2D graphics. Come check it out.

1. For simple graphics, such as rectangles, triangles. Just execute the command AREA (can be the command line input or click the corresponding command icon), after the command prompt "Specify firstcorner point or [Object /Add /Subtract]: & rdquo;, open the capture and then select the intersection of the rectangle or triangle and then back In the car, AutoCAD will automatically calculate the area (Area) and perimeter (Perimeter) and list the results on the command line.

2. For simple graphics, such as circles or other polyline (Spline) two-dimensional closed graphics. Execute the command AREA. After the command prompt “Specify firstcorner point or [Object/Add/Subtract]:”, select the Object option and select the graph to be calculated according to the prompt. AutoCAD will automatically calculate the area and perimeter.

3. For complex closed graphics consisting of simple lines and arcs, you cannot directly execute the AREA command to calculate the area of ​​the graph. You must first use the region command to create the area to be calculated as the area, and then execute the command AREA. After the command prompt “Specify firstcorner point or [Object/Add/Subtract]:”, select the Object option and select according to the prompt. Just created the area graphic, AutoCAD will automatically calculate the area and perimeter.
