How to calculate the volume and surface area of ​​an object using CAD

How to calculate volume and area using cad

There are three methods for counting area:

1. Use the command AA to point each corner point of the area in sequence, and finally get the area. Disadvantages: Not intuitive, cannot check whether there are missing points and intersections, cannot accurately measure the arc area.

Create a closed PL line by using the command PL, and then use the LI command to display information such as perimeter, area, and corner point coordinates. Certain editing capabilities for PL lines are required, especially for complex arc areas.

Use the BO command to bring up the boundary creation dialog box and select the object type as multi-line segment. Click anywhere inside the area to automatically generate a closed PL line that matches the terrain contour. After selecting the line, use the LI command to implement the operation. However, this approach has some drawbacks to be aware of. First, the original shape must be closed, otherwise the operation cannot be successful. Secondly, if there are too many primitives, the operation may not be successful.

Please choose the appropriate method according to the actual situation, and then add up the area of ​​all areas in the statistics. Select the query in the drop-down menu, then click Region/Mass Properties, and finally enter the command massprop.

How does CAD calculate the area?

After using CAD software to draw architectural drawings, you can quickly calculate the area of ​​a room or building by using the area calculation tool provided by the software. These tools often automatically calculate the area based on line and dimensional information in the drawing.

Tools/Materials

Method/Step

1. The following picture is the CAD drawing we drew. Here we need to calculate the area of ​​the room.

2. First click "Tools" "Query" - "Area".

3. Please pay attention here. Draw an endpoint. You cannot draw repeatedly here, you can only draw one line.

4. Paint along the wall as shown below.

5. When drawing to the first point, it cannot exceed the first point just drawn.

6. After drawing, press the "Enter" key to see the following picture: 16250371 here is about 16 square meters, 1000000=1 square meter.

7. If you feel unsure, you can draw 1000=1 meter. Here is a square 1000*1000=1 square.

8. After following the above steps, you can see the following picture, 1000000. The instructions are correct.
