Applying and Removing Materials Applying and Removing Materials To attach a material to an object in the drawing, you can drag the material from the materials browser and drop it onto an object. To apply a material only to a face on an object, hold the [Ctrl] key and pick the face. To apply a different material to an object, simply drag the new material to the object and pick. You can use the MATERIALATTACH command to assign materials to the layers in your drawing. Once a material is assigned to a layer, any object on that layer is displayed in the material, as long as the object’s material property is set to ByLayer. When objects are created in AutoCAD, the default “material” assigned to them is ByLayer. If your objects are organized on layers, this is the easiest way to attach mate- rials. You can override the layer material by applying a material to individual objects. Figure 17-4 shows the Material Attachment Options dialog box displayed by the MATERIALATTACH command. The list on the left side of the dialog box shows the materials loaded into the drawing. The right side of the dialog box shows the layers in the drawing and the material attached to each layer. When no material is attached to a layer, the material is listed as Global. The Global material is a “blank” material in every drawing. To attach a material to a layer, drag the material from the list on the left and drop it onto the layer name on the right. To remove a material from a layer, pick the X button next to the material name on the right side of the dialog box. The Remove Materials button on the Materials panel in the Visualize tab of the ribbon allows you to quickly set an object’s material back to ByLayer. When the button is picked, a paintbrush selection cursor is displayed. If you select an object that has a material specifi cally attached to it, the material is removed. Selecting an object already set to ByLayer has no effect.
