The mapping coordinates that you assign in the Mapping dialog box apply
to the entire selection set and remain with it. When you move the geometry,
the mapping coordinates and other mapping attributes (such as bitmap scaling)
move with it.
NOTE An object with assigned mapping coordinates attempts to maintain the
orientation of the material that is attached to it when you modify the object using
MOVE, MIRROR, ROTATE, SCALE, or other editing commands. Therefore, it is
recommended that you assign mapping coordinates even if the default coordinates
do not alter the bitmap placement. Use mapping coordinates even when the Fit
to Object option is selected in the Adjust Material Bitmap Placement Dialog Box
in RMAT.
To delete mapping coordinates assigned to an object, use the AutoLISP
®
version
of the Render mapping option, as shown in the following example:
Command: (c:setuv "D" (ssget))
Select objects: Select the objects whose mapping you want to delete
Acquire From
Temporarily closes the Mapping dialog box so that you can select a single
object in the drawing area. The object already has mapping coordinates
assigned to it—these become the current mapping settings. After you make
the selection, the Mapping dialog box is displayed again. You can click OK
immediately to accept the acquired mapping coordinates as is or use Adjust
Coordinates to modify them further.
