In this lesson, you use
Revit to adjust some settings before enhancing the scene in 3ds Max Design.
To complete this lesson,
you must have Revit installed on your workstation. If you do not
have Revit installed, proceed directly to the next lesson,
Linking a 3ds Max Design Scene to the FBX File.
Set up the lesson:
- Open the Revit application
and navigate to the \scenes\interoperability\using_autodesk_revit_files folder.
Highlight beachhouse.rvt and
NoteYou can open this
RVT file with a version of Revit that is earlier than Revit 2010,
but be aware that the user interface has changed (in particular,
the ribbon controls), and won’t exactly match the steps that are
shown this lesson.
The beachhouse.rvt project
features the model of a bungalow situated on a beach. In the procedure
that follows, you will use options in Revit to change the model’s
roof material, in preparation for exporting the scene.
NoteEven though you can
modify materials in 3ds Max Design, it is a good idea to make your changes
in Revit if this is the application you are the most comfortable
- Use the SteeringWheels controls to zoom
in on the beach house.
Change the roof material in Revit:
- Click to select the roof object, then
on the ribbon, click (Element Properties).
- On the Element Properties dialog, click
- On the Type Properties dialog Type Parameters group Construction rollout Structure item, click
- On the Edit Assembly dialog, click <<
Revit displays a panel
to the left, showing a detailed cross-section of the roof.
- In the Layers group Material column, click the top item in the
list, Roofing - Asphalt.
After you click the Roofing
- Asphalt entry, a browser icon appears. Click
Revit opens a Materials
- On the Materials dialog, click the Render
Appearance tab to display a thumbnail of the roof shingle material.
- In the Materials group, scroll down in
the list and choose Roofing - Slate.
NoteIf this material
is not available on your system, click Replace and choose an alternate
material from the Render Appearance Library.
- Click OK on all the open dialogs to exit
the material edit controls.
The texture and mapping coordinates of your
selected material will be properly transferred to 3ds Max Design, with
no further intervention required on your part.
Check light-object properties in Revit:
Like materials, all light-object
properties in the Revit scene are accurately transferred to 3ds Max Design.
Therefore, it is best to make sure that the lights you have in the
current scene possess the properties you want to use in 3ds Max Design.
- In the Project Browser panel at the left,
under Views Ceiling
Plans, double-click Level 1.
Revit displays the plan
of the ceiling.
- Zoom in to get a closer
view of the ceiling plan for the main part of the house.
There are seven ceiling
lights inside the house, and three outside on the porch.
- Click to select any ceiling light object
in the scene.
Revit displays a description of the light object
in the Element panel on the ribbon.
- On the ribbon, click (Element Properties) and
on the Instance Properties dialog, click Edit Type.
- On the Type Properties dialog Type Parameters group,
scroll down to the Photometrics rollout and review the parameters
These values, particularly Initial Intensity
and Color, will affect the rendered result in 3ds Max Design, so be
sure these parameters contain the result you are looking for. (You
can later update these values in 3ds Max Design, if you need to.)
- Click the Initial Intensity button to
view more detail on light intensity.
Note3ds Max Design uses Lumens rather than Watts
to measure light intensity. When a Revit scene is imported into 3ds Max Design, all
wattage is converted into Lumens, but intensity of the light object
is not affected.
- Click OK to exit the dialogs.
- Back in the Level 1 view, click to select
the Pendant Light object. This is the light at the lower right of
the ceiling plan, in the dining area.
- On the ribbon, click (Element Properties) to
open the Instance Properties dialog.
- Click Edit Type and review the Photometric
properties, as you did for the ceiling light object.
- Click OK to exit the dialogs.
Create a camera:
By default, the 3D view
in Revit uses an isometric perspective, but an FBX file has to contain
a single camera view. Therefore, you must create at least one camera
view in Revit before you export the scene. In this procedure, you
create a camera for an exterior viewpoint.
NoteAlthough you can
create multiple cameras in Revit, you can export only one camera
view to the FBX file.
- In the Project Browser panel, navigate
to Views Floor
Plans and double-click Level 1.
- Zoom so you have a view
of the house and the area around it.
- On the ribbon, go to the View tab.
- On the Create panel, open the 3D View drop-down list,
and choose Camera.
- Place the camera by clicking below the
reference object at the left of the scene, then click a point along
the front wall of the house, to the left of the double doors.
Revit creates a camera view. This is the view
you will initially use to render your image in 3ds Max Design. It also
changes the ribbon to show the Modify Cameras tab.
- Click (Element Properties) and
in the Element Properties dialog Identity Data rollout View Name field, change the name of the
camera to Exterior.
- Scroll down to the Extents rollout, turn
off Far Clip Active, then click OK.
With Far Clip Active turned off, the camera
will be able to detect the scene terrain beyond the bungalow model.
As with light and material properties, you can also modify clipping
parameters in 3ds Max Design if you need to.

turned off, showing scene background
TipIf you want to adjust
how the house is framed in the camera view, use the SteeringWheels
Look and Walk tools to move the camera.
Set up rendering and the sun position:
- Below the view, click (Show Rendering Dialog).
Revit opens a Rendering
Most of the rendering values do not need to
be changed, since the actual rendering of the scene will take place
in 3ds Max Design. The Scheme setting in the Lighting group is one possible
If you choose Exterior:
Sun Only from the Lighting group Scheme drop-down list, then in the 3ds Max Design scene
only the Daylight system will be turned on and all the man-made
light objects will be turned off. Conversely, if you choose Interior:
Artificial Only, only the interior man-made light objects will be
used in the scene and the Daylight system will be turned off.
- For this tutorial, we do not want to
use the interior lights yet, so leave Scheme set to the default
value, Exterior: Sun Only. (You will turn the man-made lights back
on in 3ds Max Design, when you need them.)
- For the Lighting group Sun setting, open the Sun drop-down menu
and choose Edit/New from the list of presets.
Revit opens a Sun And Shadows Settings dialog,
where you will set the geographic location and time of day for the
position of the sun created by the daylight system.
- On the Sun And Shadows Settings dialog Still tab, Sunlight
From Top Right is automatically selected from the list of single-position
(The Single Day and Multi-Day
tabs let you choose presets that animate the position of the sun
over the course of one or more days.)
- With Sunlight From Top Right selected,
Revit opens a Name dialog
for the new preset.
- In the Name dialog, type East Coast,
then click OK.
This name is appropriate because you want the
Daylight system to show the actual sun position at Cape Cod in mid-afternoon.
- In the Sun And Shadow Settings dialog Settings group, choose
By Date, Time and Place.
- Leave Place set to Boston, MA since this
city is in geographic proximity to Cape Cod. Leave the Date field
set to 5/10 and change the Time field to 3:17 PM, then
- Close the Rendering dialog.
Now you are ready to export the scene file in
Export the scene:
To export from Revit
to the FBX format, you need to be in a 3D view, such as the Exterior camera
view you have just created.
- Open the Application menu and choose
NoteAt this point, Revit
might prompt you to save the project. You don’t need to save the
project to proceed with this tutorial.
- Revit opens an Export 3ds Max (FBX) dialog.
In the File Name/Prefix field, change the name of the file to beachhouse.
If you need to, navigate to the \import\Revit_files folder
(not one of the subfolders), then click Save to export the scene.
- Minimize Revit but don’t close it, as
you will use it again later in this tutorial.
