Objects is turned on, objects assigned the same layer color become a single
3ds Max object.
Entity Names each 3ds Max object based on the object type. The object type
name is followed by a number for each object converted. For example, a Line
object becomes Line.01. Drawings can contain thousands of entities, so
deriving objects by entity can create many 3ds Maxobjects.
General Options group
Convert to Single Objects Combines multiple objects in the drawing file
into a single 3ds Max object. Objects are combined according to the current
Derive Objects By setting and their 3ds Max object type. Explicit mesh objects
are combined. Shapes with no Z axis extrusion are combined, as are shapes
with the same Z axis extrusion amount. Shapes with differing amounts of Z
axis extrusion are assigned an Extrude modifier and are not combined.
Convert Blocks to Groups Places all objects in a block entity into a 3ds Max
group that uses the name of the block entity and the number .01. For example,
a block entity named CHAIR becomes a collection of 3ds Max objects inside
a group named [CHAIR.01].
Multiple insertions of the block entity are converted to instances of the 3ds
Max group. For example, a second insertion of the block, CHAIR, becomes an
instance of [CHAIR.01] named [CHAIR.02].
When Convert Blocks To Groups is turned off, block definitions are ignored
and block insertions are treated as separate objects, similar to exploding blocks
in AutoCAD.
Skip Off and Frozen Layers Excludes the import of objects on layers that are
hidden or frozen.
Skip Hatches and Points Excludes the import of hatch patterns and point
objects.
Hatch patterns are made of many short line segments and points. Importing
all the objects in hatch patterns can overload your 3ds Max scene.
NOTE Hatch patterns are stored in drawings as anonymous blocks. Skip Hatches
And Points skips any other anonymous blocks in the drawing file. Hatch patterns
created in AutoCAD R14 are skipped regardless of this setting.
Group Common Objects Puts imported objects into a common group, based
on how they are derived. In other words, the group would include all objects
on a common layer, or color, and so on.
