DRF is the file format
for VIZ Render, a rendering tool formerly included with AutoCAD
Architecture. The DRF file type is similar to MAX files from previous
versions of Autodesk VIZ.
This file format is available
only when you use the
All DRF files must be saved as MAX files in 3ds Max. Likewise,
DRF files cannot be imported or merged into 3ds Max scenes.
NoteYou can open DRF
files using drag-and-drop functionality.
Saving DRF Files
DRF files must be saved
as MAX files in 3ds Max.
3ds Max ships with
several market-specific defaults sets. If you are working on design
visualization types of files, you should load the DesignVIZ default
settings. For more information on how to do this, see
In VIZ Render, you can
use only meters as your system unit. However, 3ds Max lets you
define your own system unit, and how units are displayed. For more
information on units, see
Using Units and
Units Setup Dialog.
Handling Linked Geometry
in 3ds Max
Linked objects show up
as Linked Geometry objects on the Modify panel. These objects don't
allow access to sub-object levels where minor editing can occur.
If a linked geometry object is moved, rotated or scaled you do have
the option to Reset Position.
Linked Geometry user
interface on the Modify panel.
3ds Max recognizes
Linked Geometry objects when you open a MAX file created in VIZ
Render. Since linked geometry objects offer no parameters on the
Modify panel, you must first add an Edit Mesh modifier to the object
or collapse the linked geometry object to an Editable Mesh in order
to access sub-object levels. If you add a modifier to linked geometry,
the modifier is applied to all instances of that object.
Linked Geometry objects
are assigned a special LinkTM controller. If the object is converted
to an Editable Mesh, Poly, NURBS or Editable Spline, the LinkTM
controller is replaced with a PRS controller.
There is no substitution
modifier in 3ds Max. However, if you open a DRF file with substituted
objects, 3ds Max will recognize the substitutions and will add
the substituted objects into the scene.
User Interface Changes
Some of the user interface
elements in 3ds Max are not where you would expect them if you
are coming from VIZ Render. For example, the
controls are in the bottom-right corner,
instead of the top-left.
For more information
on the user interface, see
The Render Presets in 3ds Max are
very different from the presets in VIZ Render. For more information
on using them, see
Preset Rendering Options.
