Understanding layers

Layers provide an additional means of structuring design entities within drawing files. You can display exactly the information you need just by switching the relevant layers on and off. This way, you can see better what you are doing and proceed quickly.

You can use layers to define the format properties of elements.

Layers are important organizational elements. Their importance increases the more people are involved in a project and the more a CAD system is used for the specialist design processes. Layers do not replace drawing files. Rather, they complement them.
