Thread Content

　　When using Haochen CAD for drawing, and it is necessary to draw tangents to two circles, how can one quickly locate the uncertain tangent points? Next, I’ll share with you the detailed step-by-step instructions. Here are the steps to draw tangent lines to circles in HaoChen CAD: 1. First, open the HaoChen CAD software, and then draw two circles in the drawing area, as shown in the figure below. 2. After drawing the circles, select the 【Line】 command from the menu bar. Hold down the 【Shift】 key before specifying the starting point of the line, then right-click the mouse. In the dialog box that appears, click on 【Tangent Point】. As shown in the figure below: 3. Then, follow the prompts to select the first 【delayed tangent point】 on the first circle, as shown in the figure below. 4. Before determining the second point of the line, hold down the 【Shift】 key first, then right-click and select the 【Tangent Point】 command; after that, select the second 【delayed tangent point】 on the other circle, as shown in the figure below. 6. Finally, press the Enter key, as shown in the figure below. These are the steps for drawing tangents to two circles using the HaoChen CAD software. If you encounter situations where you need to draw tangents to circles whose tangent point positions are not known, you can try the procedures outlined above.
