The MATERIALASSIGN command
The
MATERIALASSIGN
command (no alias) allows assigning the material defined in
the
CMATERIAL
variable to selected objects. The command just prompts for object
selection.
If specifying a material in the
PROPERTIES
palette without any selected object, we
are defining a default material for new objects, whose interest is minimal.
Exercise 11.1
To the mechanical assembly drawing used in the documentation chapter, we are go-
ing to pick some materials and assign them by layer:
1. Open the drawing
A3D_11_01.DWG
, which includes a bearing. The light-
ing is already set up to photometric, with sunlight and skylight.
2. First, verify if the model unit is correct. Applying the
UNITS
command, we
confirm that the unit is in millimeter.
3. With the
MATBROWSEROPEN
command (alias
MAT
), pick the required ma-
terials. In the
Metal
category of Autodesk Library, double-click on mater-
ials, such as
Steel
,
Steel-Cast
,
Machined 02
, and
Semi-Polished
. To
the table, select, under the
Stone
category,
Green Polished
.
4. Applying the
MATERIALATTACH
command, assign
Steel-Cast
to
bot-
tompart
layer,
Steel
to
toppart
,
Semi-Polished
to
screw
,
Machined 02
to
nut
, and
Green Polished
to
table
. Each material is dragged over the
layer name.
5. Rendering the drawing (the
RENDER
command), see all applied materials,
including the one applied to the table.
6. Save the drawing with the name
A3D_11_01final.DWG
.
