When you export a 3D view from Revit and import it to 3ds Max, you may encounter the following issues.
Slow performance when exporting from Revit 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 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 and Rendering Best Practices.
Multiple cameras not exported to 3ds Max
Revit 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 by resizing or offsetting the cropping region of the 3D view in Revit, 3ds Max does not translate the change precisely.
Solution: In 3ds Max, adjust the camera angle as needed to achieve the desired result.
