In the actual production process, 3D-3D labeling of CAD engineering drawings often uses two-dimensional labeling to represent the dimensions of engineering drawings. However, the use of engineering drawings in production or quality inspection is a bit cumbersome, and it cannot be guaranteed that every operator can understand the engineering drawings. Therefore, in three-dimensional design, how to label or understand the dimensions of engineering drawings more accurately and intuitively is a problem faced by designers and operators alike. The function of "3D measurement and marking" added in 3D CAD solves this problem well and greatly improves the user's performance.

. Let me show you the working principle of China Net 3D.

View 3D-3D marked CAD drawings

Step 1: Open the 3D drawing file drawn by China Net 3D, click the right mouse button to pop up the dialog box, and click "2D Engineering Drawing". See the following figure 1:

Figure 1/ Open the 3D2D engineering drawing of China Net.

Step 2: Select the required engineering drawing template, such as A3 drawing frame. See Figure 2 below:

Figure 2/ Selecting a Drawing Template

Step 3: Select "Axis View" in the view. See Figure 3 below:

Figure 3/ Axis View Operation

Step 4: Project into the view and select the corresponding position for projection. See Figure 4 below:

Step 5: Select the view, right-click the mouse to pop up the dialog box, and select "3D measurement". See Figure 5 below:

Step 6: You can mark the parts in three dimensions. Click the label to select and mark the part. For example, mark the distance between the two ends and the center of the circle. See Figure 6 below:

There are three main steps in drawing cad engineering drawings:

First, set the drawing boundary and determine the drawing size.

Second, draw the axis of the layer and determine the architectural framework;

Third: draw the main body of the building;

Fourth: marking papers.

Also pay attention to it and save it at any time.

CAD drawing, these are not important, what is important is to master the basic operation of drawing and practice more. After getting familiar with it, you don't even have to follow these procedures step by step, just draw a clear picture.

How to create a cad drawing 1 First open the CAD software, and then click the "File" button in the upper left corner.

2. Then click the "New" button in the new interface.

3. Then click and select the "inverted triangle icon" button in the lower right corner of the new interface.

4. Then click and select the "Open No Sample-Metric" button in the new interface.

5. Then, you can see that the cad drawing has been created in the new interface.
