Map Scaling
The scale of material textures is of primary
importance.TheFileLinkManagerorDWG/DXF
Importer attempts to read and translate the offset
andtilingofthematerialssothetexturemaps
appear in 3ds Max as they do in Revit.
However, map scaling may differ b ecause the Tile
Size settings in Revit are measured in decimal
feet or meters even if your Projec t Units are set to
Decimal Inches or Millimeters. Once the model
is linked or imported to 3ds Max, you can tur n
onUseReal-WorldScaleandmatchtheTileSize
settings. The main thing is to pay attention to t he
Tile Size settings when you create the material in
Revit.
As a example, let’s say you’ve created a material
inRevitthatusesabricktexturemapwithanX:
Tile Size set to 20 and a Y: Tile Size set to 16. If
youopenthatmaterialinthe3dsMaxMaterial
Editor, you will find that the Width and Height
Size settings are automatically set to 20’ and 16’
respectively. The texture mapping will alwa ys
be scaled correctly in the scene. How a m aterial
is displayed in the Material Editor depends on
whether Use Real-World Scale is turned on or off.

Applying Materials to Link ed R evit
Obj ects
As with models that are imported or link ed
from Architectural Desktop, there are special
behaviors exhibited with materials assigned to
linked Rev it objects. The behavior is cont rolled by
the Propagate Materials To I nstances toggle (page
2–1432).
When applying materials to a linked drawing in
3ds Max, family and type plays an important role
in material management. Assigning a material
to any component of any linked Revit object is
equivalent to assig ning the same material to ever y
instance of tha t component in every object with
thesamefamilyandtypethroughoutyourscene.
As an example, say you have multiple instances of
a Doors <Sing le-Flush : 34” x 80”> door in your
drawing, which consists of three components:
two Frame/Mu llion components representing the
inside and outside trim and a Panel component.
IfyouassignamaterialtoonePanelcomponent
anywhere in your 3ds Max scene, a ll the Panels for
all the Do ors of that family and type throughout
the scene will receive the new material.
If you want to keep materials from propagating
between instances in your scene, turn off the
Propagate Materials To Instances toggle (page
2–1432) from the Material Editor’s Options menu.

Once a draw ing is lin ked or imported to 3ds Max,
you c an modify or replace the materials. The File
Link Manager maintains a list of materials that it
links to 3 ds Max. If you change t he properties of
an assigned material while working in 3ds Max,
the new properties can get overwritten the next
time you reload an updated drawing, exported
from Revit.
