Creating and Naming Layers

You can create and name a layer for each conceptual grouping (such as walls or dimensions) and assign common properties to those layers. By grouping objects into layers, you can control their display and make changes quickly and efficiently.

When you begin a new drawing, AutoCAD creates a special layer named 0. By default, layer 0 is assigned color number 7 (white or black depending upon your background color), the CONTINUOUS linetype, a lineweight of DEFAULT (the default setting for DEFAULT is .01 inch or .25 mm), and the Normal plot style. Layer 0 cannot be deleted or renamed.

You can create new layers and assign color, linetype, lineweight, and plot style properties to those layers.

To create a new layer

  1. From the Format menu, choose Layer.
  2. In the Layer Properties Manager, choose New. A new layer is displayed in the list with the temporary name LAYER1.
  3. Enter a new name.
  4. To create more than one layer, choose New again, enter the new layer name, and press ENTER.
  5. Choose OK.

Shortcut menu Right-click in the layer list in the Layer Properties Manager, and choose New Layer.
Each new layer is numbered sequentially, LAYER1, LAYER2, and so on. You can rename a layer after it is created. The default color assigned to the new layer is color 7 (white or black depending on the background color), and the default linetype is CONTINUOUS. The default lineweight is DEFAULT (the default setting for DEFAULT is .01 inch or .25 mm), and the default plot style is Normal. You can accept the default settings or specify other colors, linetypes, lineweights, and plot styles.

If an existing layer is selected when you create a new layer, the new layer inherits the properties of the selected layer. You can modify the properties of the new layer as necessary.
If you use a specific layering scheme, you can make a copy of the layer list in your drawing and print it out for future reference.

To make a copy of a drawing layer list

  1. Enter -layer at the Command prompt.
  2. To get a list of layers in the current drawing, enter ?.
  3. Press ENTER to select all layers in the current drawing. All the layers and layer properties are listed in the AutoCAD text window.
  4. In the AutoCAD text window, scroll to the top of the layer list and select all the layers.
  5. To copy the layer list, press CTRL+C.
  6. Open a text editor and paste the layer list into a text file by pressing CTRL+V.
  7. Print the text file.
