1, for us, CAD does not display the line width by default, that is to say, when we draw with CAD, the line thickness is the same. First, we click Format at the top of the toolbar.

2. Then select the line width from the drop-down box.

3. Then we choose a good line width and click OK to modify our line width.

4, but we will find that the lines we draw are of equal width, which is the default case that CAD mentioned above does not display the line width. If we want to see the thickness of the line intuitively, we need to set the width of the display line.

5. Let's click the format on the toolbar, and then select the line width. Here, we click "Show Line Width" and then click "OK".

6. In this way, our line width is displayed, and we can find that the two line segments are displayed differently.
