file. The integrity of your other software’s design
database is never compromised by the File Link
Manager. Finally, if you decide to break a link
to a linked file, there are two options. You can
use Bind to keep the objects from the linked file
in your scene, or you can use Detach to have
them removed along with the link. For more
information, see
File Link Tips (page 3–428) .
Note: Both Detach and Bind are available from the
Files panel of the File Link Manager.
ObjectDB X Objects
3ds Max supports the display and use of custom
AutoCAD objects. These custom objects are
created u sing the ObjectDBX™ or ObjectARX
®
APIs. Applications and products that work
w ith either of these APIs can read and write to
AutoCAD draw ings, and ObjectAR X products can
extend the available feature set of AutoCAD.
Note: Toimprovefileperformance,someofthe
ObjectDBX rules have been updated. This means
that some DXF files, ones built by non-Autodesk
products or very old DXF files, may no longer
import or file link into 3ds Max.
Object Enabl ers
AutoCAD and AutoCAD vertical applications,
such as Architectural Desktop (ADT), have
custom objects that are unique to the product.
In order to v iew them in 3ds Max, you need the
appropriate Object Enabler (OE). Object Enablers
let you access, display, and manipulate these
objects in 3ds Max, as well as the other vertical
applications, including 3ds Max.
When you use the File Link Manager to Attach
a DWG file to your scene, you may encounter a
Proxy Objects Detected dialog. This means there
arecustomobjectsinthedrawingthatrequire
special Object Enablers before you can edit the
objects in 3ds Max.
Do not s how t his message a gain—Check this option
to not display this message the next time proxy
objects are detected.

Data synchronization between drawing files
created with AutoCAD, Architectural Desktop, or
Revit and 3ds Max is implemented using the File
Link Manager, which keeps drawing data linked
to the scenes. It is best understood through a few
simple principles:
• Changes in AutoCAD, Architectur a l D esktop,
or Revi t
ca n change the data viewed in
3ds Max, but changes in 3ds Max
never
change the data i n AutoCAD, Architectur a l
Desktop or Revit.
Creating a file link is a one-way process
that supports the central role of AutoCAD,
Architectural Desktop or Revit in developing
and keeping a record of your core design
database. Many changes made in AutoCAD,
Architectural Desktop or Revit w i l l appear in
