What are cad layers used for?

The functions of cad layers: 1. Control the display of graphics. For example, in a house floor plan, I can draw furniture, electrical, water supply, drainage, heating, etc. in different layers of one picture. ; 2. To control the modification of graphics, I can lock a certain layer, so I don’t have to worry about moving things that shouldn’t be moved when modifying the graphics.

Layers in CAD can quickly view graphics on a certain layer; layers can control whether graphics on this layer are printed; Figure Layers can set different line shapes, line widths, colors, etc. in different layers.

In graphic and engineering design software, there is almost always a layer, so it must have a very high value.

What is the use of layers? From my point of view, there is Here are a few points:

1. Control the display of graphics, such as a house floor plan. I can draw furniture, electrical, water supply, drainage, heating, etc. all in different layers of one picture, like this When I want to print, I can control the display of the layer to print a certain drawing.

2. Control the modification of the graphic. I can lock a certain layer, then I am changing the drawing. You don’t have to worry about moving things that shouldn’t be moved.

3. The color, line type, and line width can be set for the layer. This gives us great convenience, such as drawing mechanical drawings. You can set up several layers like this

Entity (thick solid line, black)

Label (thin solid line, green)

Invisible line (thin dotted line, black)

Center line (thin dotted line, red)

Section (thin solid line, yellow)

This way we can draw different things on different layers. Instead of setting these features one by one.
