About Layers


Layers are used to group objects in a drawing by function and to enforce standards for color, linetype, lineweight, and other properties.

Layers are the equivalent of the overlays once used in paper-based drafting. By creating layers, you can associate similar types of objects by assigning them to the same layer. For example, you can put construction lines, text, dimensions, and title blocks on separate layers. You can also organize objects by function and to assign default object properties including color, linetype, and lineweight to each layer.

Layers are an important organizational tool and can reduce the visual complexity of a drawing and improve display performance by controlling how objects are displayed or plotted.

With layers, you control the following:

Every drawing includes a layer named 0. Layer 0 cannot be deleted or renamed to ensure that every drawing includes at least one layer.

NoteIt is recommended that you create several new layers with which to organize your drawing rather than create your entire drawing on layer 0. These layers can be saved in a drawing template (.dwt) file to make them available automatically in a new drawing.
