      • Color: Displays the Select Color dialog box. Select a color value and click OK. For more information, see the section “Significance of Colors” later in this chapter.

      • Linetype: Displays the Select Linetype dialog box. Select a loaded linetype and click OK. If the linetype you want to use is not loaded, click Load and load the layer first. For more information, see the section “Defining Appearance with Linetypes, Lineweights, and Transparency” later in this chapter.

      • Lineweight: Displays the Lineweight dialog box. Select a lineweight and click OK. For more information, see “Defining Appearance with Linetypes, Lineweights, and Transparency.”

      • Transparency: Displays the Layer Transparency dialog box. Enter a new transparency value between 0 and 90, and click OK. For more information, see “Defining Appearance with Linetypes, Lineweights, and Transparency.”

      • Plot Style: Displays the Select Plot Style dialog box. From the Active Plot Style Table drop-down list, select the plot style file that you want to use for the current layout. Select one of the available plot styles to assign to the layer and click OK. (This option is available only if the drawing, drawing template, or drawing standards file is set up to use named plot styles.)

      • Plot: Toggles the plottable state of the layer. Objects on the layer that is not plottable are displayed in the drawing window but are not part of the output when the drawing is plotted or printed.

      • New VP Freeze: Toggles the freeze and thaw states of the layer when a new floating viewport is created on a named layout.

      • VP Freeze: Toggles the freeze and thaw states of the layer in the current viewport.

      • VP Color, VP Linetype, VP Lineweight, VP Transparency, and VP Plot Style: These properties can be changed just like the properties without the VP prefix previously described.

      • Description: Double-click to edit the description of the layer. Adding a description can be helpful to those new to or unfamiliar with your CAD standards.

      TIP

      Right-click the column headings in the Layer Properties Manager to control which columns you display. If there are properties that you commonly do not use, you can turn them off.

      5. Repeat steps 2–4 for each layer you want to create.

      6. Double-click one of the layers in the Layers list, select a layer from the Layers list, and click Set Current, or choose a layer from the Layer drop-down list on the Home tab ➢ Layers panel of the ribbon to set a layer as current.

Figure 2.3 Organizing objects with layers

      If you are using AutoCAD for Mac, follow these steps to create a new layer:

      1. Click Format menu ➢ Layers (or at the command prompt, enter layer and press Enter).

      2. On the Layers palette (see Figure 2.3, bottom), click New Layer.

      TIP

      If a layer already exists with the property values that are close to those you need in the new layer you want to create, select the layer that you want to base the new layer on before clicking New Layer.

      3. Enter a name that follows your company's established CAD standards.

      4. With the new layer's row selected, do one of the following:

      • On the Layers palette, click one of the columns that represents the properties of the layer.

      • On the Properties Inspector palette, on the Layer Properties tab click one of the controls to edit the property's value.

      The following explains what to do after you click on a column in the Layers palette or control in the Properties Inspector palette:

      • On (Visibility): Toggles the layer on or off. When set to Off, objects on the layer can still be selected using the All keyword at the Select objects: prompt, and the objects are regenerated when the drawing's display is updated.

      • Freeze: Toggles the freeze and thaw states of the layer. When set to Freeze, objects on the layer can't be selected using the All keyword at the Select objects: prompt, and the objects aren't regenerated when the display of the drawing is updated.

      • Lock: Toggles the lock state of the layer. The Lock setting restricts objects on the layer from being selected at the Select objects: prompt.

      • Color: Choose a color from the drop-down list or choose Select Color to display the Color Palette dialog box. Select a color value and click OK. For more information, see “Significance of Colors” later in this chapter.

      • Linetype: Choose a linetype from the drop-down list or choose Manage to display the Select Linetype dialog box. Select a loaded linetype and click OK. If the linetype you want to use is not loaded, click Load and load the layer first. For more information, see “Defining Appearance with Linetypes, Lineweights, and Transparency” later in this chapter.

      • Lineweight: Choose a lineweight from the drop-down-list. For more information, see “Defining Appearance with Linetypes, Lineweights, and Transparency.”

      • Transparency: Click and drag the slide to specify a new transparency value. For more information, see “Defining Appearance with Linetypes, Lineweights, and Transparency.”

      • Plot Style: Choose a plot style from the drop-down list.

      • Plot: Toggles the plottable state of the layer. Objects on the layer that is not plottable are displayed in the drawing window, but the objects are not part of the output when the drawing is plotted or printed.

      • New VP Freeze/Freeze In New Viewports: Toggles the freeze and thaw states of the layer when a new floating viewport is created on a named layout.

      • VP Freeze/Viewport Freeze: Toggles the freeze and thaw states of the layer in the current viewport.

      • VP Color, VP Linetype, VP Lineweight, VP Transparency, and VP Plot Style: These properties can be changed just like the properties without the VP prefix previously described.
