Import Settings Dialog for Revit Files

Provides options for Revit file import.

• File menu > Import > Select File To Import dialog > Files Of Type drop-down list > Choose Revit importer (*.RVT).

Select Revit View

Use the list to choose the Revit camera view to load.

Revit files can contain multiple camera views, but when you import a RVT file, you must choose a single camera view.

Combination Rule

Use this drop-down list to choose the way in which Revit entities are combined. Combining entities can reduce the number of objects in your 3ds Max scene, and improve performance.

• Do Not Combine Entities (The default.) Imports each Revit object as a single 3ds Max object.
• Combine By Revit Category Revit objects in the same category become a single 3ds Max object. The object has the name of the category and is placed on a layer with the same name. The family and category appear in the 3ds Max Scene Explorer.

  Multi/Sub-Object material information is retained.

• Combine By Revit Family Type Revit objects belonging to the same Family Type become a single 3ds Max object. The object has the name of the family type and is placed on a layer with the same name. The family and category appear in the 3ds Max Scene Explorer.

  Multi/Sub-Object material information is retained.

• Combine By Revit Material Revit objects assigned the same material become a single 3ds Max object. The object has the name of the material, and is placed on a layer with the same name. Revit metadata (family and category) does not appear in the 3ds Max Scene Explorer.

  Multi/Sub-Object material information is lost.

  Note: If the Revit scene does not contain material assignments, the geometry is imported as a single object, and this option becomes comparable to the As One Object option.
• As One Object Imports the entire Revit drawing as a single 3ds Max object, with the name of the camera view. The object is placed on a layer with the same name. Revit metadata (family and category) does not appear in the 3ds Max Scene Explorer.

  Revit materials are combined into a single Multi/Sub-Object material.

  Tip: This option is useful if you are doing a massing study such as a shadow animation.

Revit View Detail Level

Use this drop-down list to choose the level of detail you want to view. Options include:

• default
• coarse
• medium
• fine.

Objects group

Chooses which kind of geometry to import from the RVT file. Objects include:

• materials
• cameras
• daylight system
• lights
• RPCs (Rich Photorealistic Content including people, trees, plants, etc.)
• BIM Info (Building Information Modeling data).

Geometry group

Curved Objects Detail

Controls the number of segments (the resolution) of curved objects. Default=8. Higher values result in smoother surfaces.

Simplify Mesh

Lowers the polygon count by reducing coplanar triangles. The higher the value, the more the resulting mesh can differ from the original.

Optimize Extrusion

Reduces the number of triangles by rebuilding extruded polygons. This creates smoother, editable geometry; as opposed to creating an editable mesh with non-editable, tesselated geometry.
