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 additional information, “Revit data,” such as their originating Category, Family, Type, and Material.
The File Link Manager and DWG/DXF Import functionality looks for and processes this additional information. When “Revit data” is found with an object, the object is treated differently by the import/file link process. The primary differences are:
Whenever you use the File Link Manager or DWG/DXF Import functionality, 3ds Max detects a useful distinction between categories of a Revit elements. It automatically separates names and groups the elements in 3ds Max to make them easier to work with.
The topics in this section described suggested settings for Revit projects, and the suggested workflow from Revit to 3ds Max.
When you export a DWG or DXF from Revit projects, materials are translated into a format that 3ds Max can understand. Revit creates materials in the same format as used by AutoCAD Architecture, VIZ Render and 3ds Max.
