controllers. Each nested block maintain its parent-child hierarchy and is
imported as “Block/Style Parent”. In addition, if a single drawing object creates
both mesh and spline geometry, you will find objects referred to as “Linked
Geometry” in the scene. Block/Style Parent and Linked Geometry objects
appear in the modifier stack on the Modify panel.
NOTE If you import multiple drawings, the importer merges the drawings together.
If you are using AutoSurf or AutoCAD Designer, use the AutoCAD command
3DSOUT to export mechanical models to 3ds Max. You can also explode the
mechanical models and then import the resulting file, but some data will not
appear in the AutoCAD drawing file.
IMPORTANT AutoCAD and its vertical applications, such as AutoCAD Architecture
(formerly ADT), have custom objects that are unique to the product. In order to
view them in 3ds Max, you need the appropriate Object Enabler (OE). Object
Enablers let you access, display, and manipulate these objects in AutoCAD, as well
as the other vertical applications, including 3ds Max. For a list of downloadable
OEs, see the http://www.autodesk.com/autocad-object-enablersAutodesk Web site
Legacy DWG Importer
The current DWG import utility contains many improvements, including
enhanced DWG compatibility and greater user control and customizability;
however, some features were lost from the DWG Importer found in previous
versions of the software. For this reason, 3ds Max retains the
legacy DWG
Import functionality
on page 6998 .
Support of Multiple Materials on Imported ACIS Solids
3ds Max supports multiple materials per object in DWG files exported as ACIS
solids from Revit Architecture/Structure/MEP 2008 and later, as well as solid
primitives created in AutoCAD Architecture 2008 (formerly ADT) and later.
Imported solids can have
Multi/Sub-Object materials on page 5558 that you
can view and manipulate in the Material Editor.
NOTE Previous versions of 3ds Max supported multiple materials for polymeshes
but only one material ID for each ACIS solid when importing a DWG file, regardless
of how many material IDs had been assigned to the solid.
NOTE Legacy AutoCAD DWG import does not support multiple materials on ACIS
solids.
