Introduction to CAD* Tutorial: How to quickly calculate the area of ​​complex graphics?

Thread Content

In the process of drawing using Haochen CAD drawing software, a very complex figure is drawn. What should I do if I want to calculate the area of ​​the figure? Next, I will share with you an introduction to CAD * Tutorial: How to quickly calculate the area of ​​complex graphics! The steps to calculate the area of ​​complex graphics in CAD are as follows:: 1. First open the Haochen CAD software, then create the file [CAD Area Query] and draw the graph as follows. The graph consists of white area B and yellow area A. What needs to be found is the area of ​​yellow area A. As shown below: 2. Remove the filling part as shown below: 3. Click the [Drawing] drop-down menu and click [Area] ； 4. Select the outer contour of area A, as shown in the figure, and press the right mouse button or Enter to confirm. We have created a region with an outer contour as shown by the dotted line in the figure below. As shown below: 5. Continue to create area B, select the outline outside area B, as shown in the figure below, and press the right mouse button or Enter key to confirm. As shown below: 6. Open the [Tools] drop-down menu [Query] and click "Area. 7. Open the area measurement command, enter the shortcut command [O], press the Enter key to confirm, and select the area object A just created. 8. From the picture below, we can see that the area of ​​the green area is S1=29.1211mm2. As shown below: 9. Next, we will find the area of ​​area B. Press the Enter key and press Enter to continue the area measurement command. Enter "o" and press Enter, press Enter, and select the area object B just created. 10. We get the area of ​​area B to be 6.2180mm2, so we can get the area of ​​area A that we want as S1-A=29.1211mm2. The above is a tutorial on how to measure the area of ​​complex graphics in Haochen CAD drawing software. I hope it will help people who are just starting to learn CAD. * My friends are helpful.~
