IPT and IAM are the
native Autodesk Inventor® file formats for parts (IPT)
and assemblies (IAM). You can import
both file formats into 3ds Max Design.
New in Autodesk 3ds Max Design 2011 is the
ability to import Inventor files as Body Objects. This allows geometry
in the ACIS solids format to remain in that format while in 3ds Max Design.
To output this format, use the
The components of models
that you import into 3ds Max Design retain their object naming as assigned
in Autodesk Inventor and can be brought in either as
editable meshes or
Body Objects. Once imported, you can edit the model just as you
would any other type of object that you construct. You can apply
modifiers, alter materials, add lighting and cameras, create animations,
and so on.
Requirements and Limitations
Limitations of the Inventor
Import feature are as follows:
- Camera animation paths are not converted
to 3ds Max Design cameras so any animation you've set up in Inventor is
lost during import.
- Any lighting from brightness and ambience
settings created in the Inventor file are not imported. You will
have to relight the scene once the import is complete.
- A model that is set up with constraints
to limit the movement of parts will lose those constraints upon
import. You will need to use
kinematics (IK) to restore the constraints.
- Dragging and dropping an Inventor file
into 3ds Max Design uses the settings last set on the Inventor File
Import dialog with the except for Mesh Resolution, which always
resets to 0.
Materials and material
assignments made to the original Inventor model are retained and
imported along with the geometry. Materials are imported as
Architectural materials or
if a single object has several materials assigned to it, they are
imported as a
To import an IAM or IPT file:
Application menu Import.
- Choose Autodesk Inventor in the Files
Of Type list.
- Specify a file name to import.
- Set options in the Autodesk Inventor
File Import dialog.
To retain the solid-geometry
format from Inventor, set the Import As option to Body Objects and
follow the procedures in
Import As group
- Import As
Choose the format in which
the Inventor file is imported:
- Body ObjectsImports
the Inventor file in the
Body Objects format also
used when importing SAT files, which retains all ACIS solids information.
To save these objects as solids, use the SAT exporter.
the Inventor file as
editable mesh objects.
Use the Mesh Resolution setting (see following) to determine the
fineness or coarseness of the imported mesh.
Assembly Options group
- Reference Duplicate Parts
When on, the importer treats
duplicate parts in the Inventor file as references of each other.
- Create Layers by Material
Generates layer information
based on incoming materials. All objects sharing a material will
be placed on the same layer.
- Add Object Name to Material
When importing materials,
uses the imported material name as part of the object name.
Merge/Replace Options group
- Merge/Replace Option
Choose how the importer
treats current scene contents:
- Merge With Current SceneIncoming geometry
is merged with any existing geometry in the scene. This setting
is useful for combining components from separate files into a single
- Completely Replace Current
SceneThe imported data completely replaces any existing geometry
in the current scene. If the current scene has not been saved, you
are given the opportunity to save the scene before proceeding with
the import process. This is the default choice.
Material Options group
- Import Inventor Materials
When on, all Inventor materials
and texture maps are translated and imported into the scene. When
off, no materials are imported with the model.
- Assign Material IDs
Lets you control whether material
IDs are assigned to objects that are imported from Inventor. You
can assign different materials to different surfaces of the same
object while working in Inventor. When these objects are imported
to 3ds Max Design, material IDs are assigned to the faces of single
objects to which multiple materials are applied.
For example, say you've
created a single object that represents a knob with a threaded shaft
and you've applied a black, plastic material to the knob and a silver,
metal material to the threaded shaft. If Assign Material IDs is
on when you import the model into 3ds Max Design, the imported faces
that have the plastic material are assigned 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 Design,
you can quickly make
sub-object selections based on
the material IDs or apply a
Multi/Sub-Object material that contains
materials that correspond to the IDs assigned to the faces.
Mesh Resolution group
- Mesh Resolution
When importing as meshes,
this slider lets you determine the degree of refinement applied
to the mesh objects. When set to 0 (zero), the geometry is imported as
it appears in Autodesk Inventor. When set less than zero, the mesh
is optimized with fewer faces, thus reducing detail. If the mesh resolution
is set higher than zero, the mesh is tessellated with more faces,
providing 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.
NoteThe option to adjust
mesh resolution is available only for models imported from Autodesk
Inventor 10 or later.
Inventor File Vertical
This option determines
the model's orientation upon import. You can choose which axis of
the Inventor model is vertical.
- Inventor File Vertical Direction
Choose the axis option:
- X AxisThe
X axis of the model, as seen in Inventor, is rotated so it is vertical when
the model is imported.
- Y AxisThe model
is imported with the Y axis oriented as the vertical axis.
- Z AxisThe imported
model is rotated so its Z axis is the vertical axis.
