Why are the printing lines and drawing lines inconsistent in CAD drawing?

If you paste it into a word document and print it out, then this is normal. If you print directly with cad, it is because the print line width is not set in the print settings, and the object line width is used. Click Print to set the line width column: Use the line width of the object, and then print. In addition, when you start drawing, you can use layers, use a layer of one color as the thick line you want to use, and use a layer of another color as the thin line, and then set the line width of the color directly when printing settings. It's simple. You can understand it once.
