The HaoChen CAD drawing software includes several CAD capture commands that can be used directly, making the process much simpler and more convenient compared to using auxiliary lines for drawing. Next, I’ll introduce you to the usage instructions for the MTP capture command! Let’s explain the specific steps with an example: 1. First, open the HaoChen CAD software. As shown in the diagram below, there are two rectangles; we will draw a circle in the area between these two rectangles. 2. Click the [Circle] button on the toolbar on the left side of the CAD software interface, or directly enter the CIRCLE command in the command line. 3. Do not perform any operations; simply enter the MTP command and press Enter. 4. Specify the first and second points according to the instructions displayed in the command line. Here, we select the top-left corner point of the left rectangle and the bottom-right corner point of the right rectangle to determine the center of the circle. As shown in the figure below: 5. In this way, we can draw a circle at the middle of the two rectangles. As shown in the figure below: There are actually many other ways to obtain drawings with the same result, but those methods are all quite complicated; only the method using the MTP capture command mentioned above is the simplest and most convenient. So, those who are just starting to learn *CAD must master these common CAD commands, as they can greatly improve drawing speed~
