Attaching materials

Once you have imported, created, and modified the materials you need, you can

attach them to objects. AutoCAD lets you attach materials by object, layer, or color.

To attach any material, follow these steps:

1.    Choose Materials from the Render toolbar.

2.    Choose the material from the list of materials.

3.    Use one of these methods to attach the material:

•    Click Attach to attach a material by selecting the object or objects. AutoCAD temporarily returns you to your drawing and prompts you to select objects.

•    Click By ACI (AutoCAD Color Index) to attach a material by its color in the drawing. AutoCAD opens the Attach by AutoCAD Color Index dialog box, which lets you choose a color, or colors, by their numbers.

•    Click By Layer to attach a material by layer. AutoCAD opens the Attach by Layer dialog box, which lets you choose a layer or layers.

Attaching materials by layer can be a very efficient method. It requires some planning in advance. For example, if you have a block that is a chair, and if you create it so that the legs are on one layer and the seat and back are on a second layer, then you can easily attach a wood-like material to the legs and a nice pattern to the seat and back.

You can assign a material to an object, to its layer, and to its color, which would mean that the object has three materials. AutoCAD gives priority to direct attachments by object, then to attachments by color, and finally to attachments by layer.
