Settings for CAD layers
Thread Content
What are the common types of layer settings? Are there standards for the line styles and widths of various layers?
There is no standard for setting layers; decide based on your own needs. Of course, a single layer can only have one line width.

It’s purely a matter of personal preference – there are no rules regarding how many layers to use or how to define them
Layers exist primarily so that those who create CAD drawings can select a range of objects they want to work with as quickly as possible. For example, when drawing architectural plans, windows, doors, walls, axes, text, and annotations can be placed on different layers. If the axes in a drawing serve only as a helper tool and are not essential, it’s necessary to delete them once the drawing is completed. In such cases, the layer containing the axes can be set as the current layer, while other layers can be frozen or turned off in the layer manager (freezing essentially means hiding, and turning off also serves to hide elements); alternatively, layers can be locked (elements on locked layers remain visible but cannot be modified). The use of these buttons often depends on an individual’s preferred working habits.
I’ve learned about the common layers used in CAD for mechanical drawing, but what are the common layers used in process drawings?
Reply to Floor 2 and Floor 5: Usually, that is indeed the case (including myself), but there are **standard specifications in GB/T 18229-2000 for the line styles and widths of each layer; it’s not something that can be decided arbitrarily.
I’ve learned something from this; thank you. I realize I was quite stupid before
Generally, only the center line is drawn with a dotted line, auxiliary lines are drawn with dashed lines, main lines are drawn with solid lines; main lines are thick while secondary lines are thin. The color can be chosen according to personal preference – there are no rules regarding this
Layers are a tool for auxiliary classification; it depends on how you decide to use them. If there is no software support or restrictions, just get used to working in that way, but be sure to keep things consistent with those around you
