You can set the following properties for Layers: LineColor, LineStyle, LineWeight, transparency, PrintStyle, and a description.
Most of the Layer properties can be modified using the Layers Manager.
Home > Layers > Layers Manager.
LineColor
When you start a new drawing, new Layers are automatically assigned the color white. When you create a new Layer, the Layer adopts the color of the selected Layer.
Entities you draw on the Layer appear in the assigned Layer color except those to which you specifically assign a LineColor directly.
To set Layer LineColors:
In the Layers Manager dialog box, double-click the LineColor cell you want to change.
Select a LineColor or select Specify Color for more colors.
The LineColor for the Layer is set. When you change the color, all entities on the Layer that were sketched with the color designated as ByLayer appear with the changed color. Entities on the Layer that were sketched with a color other than the ByLayer color are not affected.
LineStyle
When you start a new drawing, new Layers are automatically assigned the continuous LineStyle. When you create a new Layer, the Layer adopts the LineStyle of the selected Layer.
Entities you draw on the Layer appear in the assigned LineStyle except those to which you assign a LineStyle directly.
To set Layer LineStyles:
In the Layers Manager dialog box, double-click the LineStyle cell you want to change.
Select a LineStyle or select Other to load a new LineStyle in the Line Style dialog box.
The LineStyle for the Layer is set. When you change the LineStyle, all entities on the Layer that were sketched with the LineStyle designated as ByLayer appear with the changed LineStyle. Entities on the Layer that were sketched with a LineStyle other than the ByLayer LineStyle are not affected.
LineWeight
When you start a new drawing, new Layers are automatically assigned the default LineWeight. When you create a new Layer, the Layer adopts the LineWeight of the selected Layer.
Entities you draw on the Layer appear with the assigned LineWeight except those to which you assign a LineWeight directly.
To set Layer LineWeights:
In the Layers Manager dialog box, double-click the LineWeight cell you want to change.
Select a LineWeight.
The LineWeight for this Layer is set. When you change the LineWeight, all entities on this Layer that were sketched with the LineWeight designated as ByLayer appear with the changed LineWeight. Entities on the Layer that were sketched with a LineWeight other than the ByLayer LineWeight are not affected.
Transparency
You can specify the transparency level for specific Layers. When you start a new drawing, new Layers automatically have no transparency. When you create a new Layer, the Layer adopts the transparency of the selected Layer.
Entities you draw on the Layer appear with the assigned transparency except those to which you assign a transparency directly.
To set Layer transparency:
In the Layers Manager dialog box, double-click the Transparency cell to change.
Specify a value between 0 and 90% where 0% means no transparency (opaque).
The transparency for the Layer is set. When you change the transparency, all entities on the Layer that you created with the transparency designated as ByLayer appear with the specified transparency. Entities on the Layer that you created with a transparency other than ByLayer are unaffected.
PrintStyle
You can specify whether to print the content of specific Layers with indivual PrintStyles. When you create a new Layer, the Layer adopts the PrintStyle of the selected Layer.
Entities you draw on the Layer appear with the assigned PrintStyle except those to which you assign a PrintStyle directly.
To set Layer PrintStyles:
PrintStyles are only valid if the drawing uses named PrintStyles (.stb files), not color-dependent PrintStyles (.ctb files). You can set named PrintStyles in Tools > Options > System Options > Printing > Default settings > Default type.
In the Layers Manager dialog box, double-click the PrintStyle cell you want to change.
Select a PrintStyle or select Other to load a new PrintStyle in the Print Styles dialog box.
Description
Optionally you can add a description for each Layer.
To add Layer descriptions:
In the Layers Manager dialog box, double-click the Description cell you want to add.
Type a description, then press Enter.
