Copyright Goodheart-Willcox Co., Inc. 474 AutoCAD and Its Applications—Advanced option of the command restores the default mapping to the object. The Switch mapping mode option allows you to change between the four types of mapping. If the command is typed, there is an additional option. The Copy mapping to option provides a quick and easy way to apply the changes made to the current object to other objects in the scene. Enter this option, select the face or object to copy from, and then select the faces or objects to copy to. This option is also available if the Switch mapping mode option is entered. For example, look at Figure 17-37A. The grain on the stair risers is running verti- cally when it should run horizontally. First, apply a planar map gizmo to the bottom riser. Next, rotate the mapping 90°, Figure 17-37B. Finally, use the Copy mapping to option to copy the mapping to the other risers, Figure 17-37C. NOTE NOTE Mapping coordinates can be applied to 3D-mapped (procedural-mapped) materials, but adjusting the coordinates has no effect. This is because the 3D map is generated from mathematical calculations based on the world coordinate system. A 3D-mapped material must be adjusted at the material level.
