exporting a Revit project, you may be able to take advantage of 3ds Max functions that will streamline the
process and help you achieve the desired results faster and with less effort.
Exporting to FBX
1 In Revit Architecture, open a 3D view, and prepare it for export.
See Before Exporting a 3D View to 3ds Max on page 1374.

FBX.
TIP If FBX displays as gray, open a 3D view of the project. Then try again.
3 On the Export 3ds Max (FBX) dialog, for Save in, navigate to the target folder for the exported
file.
4 For Naming, do one of the following:
■ To specify a file name manually, select Manual (Specify file name). For File name/prefix,
specify the name of the output file.
■ To use an automatically generated file name, select Automatic – Long (Specify prefix), or
Automatic – Short. See
File Names for Exported Files on page 1353.
5 Click Save.
Revit Architecture generates the FBX file and places it in the target location.
You can now import the FBX file into 3ds Max, using the 3ds Max FBX plug-in. For more information, refer
to the 3ds Max Plug-in documentation.
3ds Max provides additional control over materials, beyond the capabilities of Revit Architecture. To activate
the Revit material assignments and lights in 3ds Max, specify mental ray
®
as the rendering engine. This is
the default render setting for 3ds Max Design. For more information, refer to the 3ds Max documentation.
Troubleshooting Exports to 3ds Max
When you export a 3D view from Revit Architecture and import it to 3ds Max, you may encounter the
following issues.
Slow performance when exporting from Revit Architecture and importing to 3ds Max
Performance may be slow for large projects that contain lots of objects and their data. To improve performance,
limit the model geometry being exported. In Revit Architecture you can use a section box, hide categories
of model elements that you do not need for the scene, and set the detail level as appropriate. See
Limiting
Model Geometry Before Exporting on page 1342 and Rendering Best Practices on page 1233.
Multiple cameras not exported to 3ds Max
Revit Architecture exports to FBX only one camera, which corresponds to the active 3D view. As a result,
only the current Revit 3D view or camera will be imported into 3ds Max as a 3D camera view.
Incorrect camera angle in 3ds Max
Symptom : When you export a Revit 3D view to FBX and import it into 3ds Max, the camera angle may not
reflect the angle of the Revit view.
Issue : 3ds Max does not support the cropping region and optical center of Revit cameras. However, the field
of view (FOV) or perspective of the Revit cameras will be correct in 3ds Max. If you modify the Revit camera
