There are six options to choose from:
■ Layer, Blocks as Node Hierarchy Linked objects on a given layer in the
AutoCAD drawing that aren't in blocks are combined into a single Editable
Mesh or Editable Spline object in 3ds Max. The name of each linked object
is based on the AutoCAD object's layer. The linked object name has a
“Layer:” prefix and is followed by the layer name. For example, all AutoCAD
objects residing on the layer Walls become part of the Editable Mesh named
Layer:Walls after they are linked in 3ds Max.
Each block is linked separately as a hierarchy, with the block itself as the
parent object and its constituent parts as child objects. The child objects
of the block are combined by layer.
TIP This is usually the best option for file linking. It preserves all ADT
information, and generally maintains the same granularity as you would expect
in AutoCAD.
■ Layer, Blocks as Node Hierarchy, Split by Material This works the same
as the Layer, Blocks as Node Hierarchy option, with the following additional
functionalities: The combination of non-block objects by layer, followed
by material and support for multiple materials assigned to ACIS solid and
polymesh geometry.
■ Non-block object layer combination:
For example, take an AutoCAD file with six objects in layer A: three have
a Brick material and three have a Stone material. Using this option, this
file would be linked to in the form of two objects, or nodes, one containing
the Brick material and the other with the Stone material.
Each block is linked to separately as a hierarchy, with the block itself as
the parent object and its constituent parts as child objects. The child objects
of the block are combined by layer.
■ Multiple material support
On import, ACIS solids and polymesh geometry can support multiple
materials. For polymesh geometry, one material is supported per face. For
an ACIS solid, if the solid has more than one material associated with it,
a multi/sub object material is created that contains the materials used. If
the solid has only one material associated with it, a standard/architectural
material is assigned instead.
