Do you have to learn to use layers when drawing CAD?

Yes, you must learn to use layers when drawing CAD. In the process of drawing construction drawings, lines are very complicated and difficult to distinguish, so you need to add layers to distinguish lines.

The specific method comprises the following steps:

1. After downloading and installing the software, first open the CAD main interface.

2. Click the three-layer overlay pattern in the upper left corner to open the controller of the layer.

3. After opening the layer controller, you can click "New Layer" in the upper left corner to create multiple layers, and adjust the layer style by modifying the added layers.

4. Next, you can modify the color, line type and line width of each layer, and adjust the parameters of each layer according to your own needs.

5. White is named the wall, green is named the window, and the line is hidden by the lower layer.

6. Double-click the inside of the second box, then click "Layers", select the layer to hide, and then click the third one in front to hide the lines in the double-click box, which is the advantage of layers.
