way would appear in 3ds Max assigned to the linked AutoCAD Architecture
objects. However, this practice is not recommended because the native 3ds
Max Architectural materials have more complete information on the surface
characteristics of objects, and are easier to create and share. In other words,
you work faster, share easier, and get better results using native 3ds Max
rendering materials in both AutoCAD Architecture and 3ds Max.

UVW Mapping in AutoCAD Architecture Objects
An important consideration in how many materials render is how they are
“mapped” to the surfaces of the objects they are assigned to. This is especially
important for materials that use
bitmaps on page 7730 to define the diffuse
color of a material, or the bump and cutout special effects. As an example,
you may have scanned a picture of wood grain for use in a material, but when
the material is applied to an object, how large should the image of the wood
grain be? Which way do you want the grain to run, and how do you want the
grain to wrap around the corners of a three-dimensional object?
How two-dimensional maps are applied to three-dimensional surfaces is
represented by
mapping coordinates on page 7838 , which are stored as UVW
coordinates
on page 7962 . In cases where mapping coordinates are likely to be
important to the rendered appearance of an object, AutoCAD Architecture
(formerly Architectural Desktop) assigns UVW coordinates to object
components. 3ds Max translates these coordinates and stores them in the
object mesh that is displayed and rendered in the 3ds Max scene. You can
adjust these coordinates in 3ds Max using the
UVW Xform modifier on page
1872 , or you can redefine them all at once using the
UVW Map modifier on
page 1849 .
IMPORTANT Make sure that Rescale is turned on in the Attach Panel of the File
Link Manager dialog. Otherwise, if the units do not match, the UVW coordinates
will be incorrectly scaled when linked to 3ds Max.
Drawings Exported from Revit
The Export function in Autodesk Revit lets you export models to DWG or DXF
file formats. In Revit 6.1 and 7.0, the exported drawing entities contain
