In-Depth Information
•
Reset mapping
: This option restores the original mapping coordinates
•
Move
: This option displays the
3DMOVE
gizmo and grips, allowing you to
move the material on the object by specifying two points
•
Rotate
: This option displays the
3DROTATE
gizmo, allowing you to rotate
the material on the object by specifying a rotation axis and a point to in-
dicate rotation angle
•
Reset
: This option restores the original mapping coordinates
•
Switch mapping mode
: This displays the initial prompt, allowing you to
select a different geometry
Note
The command does not allow you to specify direct values for moving or rotating
coordinates, which is a severe limitation.
Sometimes, AutoCAD is not able to display correct mapping coordinates. In
these situations, applying this command should correct the problem.
Exercise 11.3
Applying materials to a simple roof, we will demonstrate how to adjust mapping co-
ordinates and how to assign a different material to faces:
1. Open the drawing
A3D_11_03.DWG
. The lighting is already set up to pho-
tometric, with sunlight and skylight.
2. With
MATBROWSEROPEN
, load the
Spanish Tile - Red 2
material (the
Roofing
library). Also create a new
Wall Paint
material.
3. Editing the first material, access the
Generic
image palette, activate
Link
texture transforms,
and assign
Sample Size
the value
2
in width.
4. Editing the second material, just modify its name to
White Inner
walls
.
5. For this simple case, instead of assigning materials by layer, drag the ma-
terial from the
Materials Browser
palette to the roof. We can immediately
see that the material is not applied correctly.
