Layers are used to group information in a drawing by function and to enforce linetype, color, and other standards.
Layers are the equivalent of the overlays used in paper-based drafting. Layers are the primary organizational tool used in drawings. Layers group information by function and to enforce linetype, color, and other standards.
Similar types of objects are usually assigned to the same layer. For example, construction lines, text, dimensions, and title blocks are usually assigned to separate layers. You can control the following:
- Whether objects on a layer are visible or dimmed in any viewports
- Whether and how objects are plotted
- What color is assigned to all objects on a layer
- What default linetype and lineweight are assigned to all objects on a layer
- Whether objects display with different layer properties in individual layout viewports
