Process
When 3ds Max links a ACIS solid DWG file from AutoCAD or Revit
Architecture (version 2008 and later) with either the Layer, Blocks as Node
Hierarchy, Split by Material” or the Entity, Blocks as Node Hierarchy derivation
methods, multiple material IDs are read and editable as Multi/Sub-Object
materials in the Material Editor.
3ds Max reads each face of a linked ACIS solid to determine if it contains any
material IDs that it can read. If more than one material ID is read from a solid,
each material ID is translated to a material ID on file link and re-assigned to
the object.
The program creates Multi/Sub-Object materials only if more than one material
ID is found; if an ACIS solid contains only one material ID, a standard
architectural material is created and assigned instead.
NOTE 3ds Max first evaluates the linked file to find any Revit material IDs, and
then looks for AutoCAD material IDs.
NOTE If you link a DWG file with the Layer, Blocks as Node Hierarchy, Split by
Materials” derivation method, the solid is not split to reflect its materials set.
Multi/Sub-Object Material Naming
In earlier versions, 3ds Max read the material ID information from the color
ID of the AutoCAD/Revit material ID’s face. Now, 3ds Max creates a
Multi/Sub-Object material for every translated per face material ID each time
you link a DWG file that contains an AutoCAD/Revit solid.
When the program finds multiple materials assigned to an ACIS solid and
creates a Multi/Sub-Object material, it consists of instances of standard
architectural scene materials.
Naming Conflicts
Material IDs are unique within one DWG file. However, the same material ID
may appear in two different files, such as Basic Wall: Generic – 12” Masonry.
If a naming conflict arises when two scenes are merged, the program applies
the last loaded material used in the Multi/Sub-Object material.
For example, if file1.dwg and file2.dwg both contain a material named Brick,
and they are both linked, the Brick material used is the one from the second
file (file2.dwg).
