2. Select the rectangle tool in the toolbox and press the shortcut key U to create a rectangle with a width of 620 and a height of 180.
3. Move the created rectangle tool to a suitable position on the page, continue to select the rectangle shape tool, and press the shortcut key U to change the fill color to colorless and the stroke color to deep red, as shown in the figure.
4. Change the thickness of the line and draw a thin line, which can be set to 0. 1. To demonstrate the effect, I don't draw too thin lines. I choose the line thickness as 1 point and the line shape as dotted line.
5. Select a rectangle, then use the path selection tool to select the path of the rectangle, and then use the pen tool to delete one of the four nodes.
6. Then use the path selection tool, select another node below, use the delete tool, delete it directly and click next to it, so that the dotted line is drawn.
7. After drawing, if you think the lines are too short and thin at this time, you need to modify them. You need to change the thickness and use the rectangle selection tool, and repeat step 4. If the rectangle is long, you can move the nodes. It can also be diagonal or curved.
8. If you want to customize the line type, you can set it in more options of stroke options, as shown in the figure. It's done.
