Importing Autodesk Inventor Files 555
Material Options group
Impor t I nventor Materials—When turned on, all
Inventor materials and texture maps are translated
and imported into the scene. If turned off, no
materials are imported with the mo del.
Assign Materi al IDs—Lets you cont rol whether
material IDs are assigned to objects that are
imported from In ven tor. You can assign different
materials to different surfaces of the same object
while working in Inventor. When these objects are
imported to 3ds Max, material IDs are assigned
to the faces of single objects to which multiple
materials are applied.
Forexample,you’vecreatedasingleobjectthat
represents a knob that has a th readed shaft and
you’ve applied a black, plastic material to t he knob
and a silver, metal material to the threaded shaft. If
AssignMaterialIDsisturnedonwhenyouimport
themodelinto3dsMax,thefacesoftheobject
that have the plastic material are assig ned material
ID #1 and the faces that have the metal material
are assigned material ID #2. If you choose to try
different materials while working in 3ds Max,
you can quickly make
sub-object selections
(page 1–74)
based on the material IDs or apply
a
Multi/Sub-Object material (page 2–1403) that
contains materials that correspond to the IDs
assigned to the faces.
Mesh Resolution group
Mesh Resolution—This slider lets you determine
the degree of refinement applied to mesh objects
by the importation process. When set to 0 (zero),
the geometr y is imported as it appears in Autodesk
Inventor. When set less than zero, the mesh is
optimized w ith fewer faces thus reducing detail.
If the mesh resolution is set higher than zero, the
mesh is tessellated with more faces, giving you
greater detail.
The mesh resolution slider is always set to 0 when
you initiate an import.
Left: Mesh Resolution=–7.
Center: Mesh Resolution=0.
Right: Mesh Resolution=+7.
Note: The option to adjust mesh resolution is
available only for models imported from Autodesk
Inventor 10 or later.
Inventor File Vertical Direction gro up
This option determines the model’s orientation
upon import. You can choose which axis of the
Inventor model is vertical.
XAxis—TheXaxisofthemodel,asseenin
Inventor , is rotated so it is vertical when the model
is imported.
YAxis—The model is imported with the Y axis
oriented as the vertical axis.
ZAxis—The imported model is rotated so its Z axis
is the vertical axis.
