Import a 3D Shape

Open a Revit project or family, and use the Import CAD tool to import 3D geometry from supported applications.

For information about how imported 3D shapes can be used in families and projects, see About Importing 3D Shapes.

To import a 3D shape

1. Open the project or family into which you want to import the 3D geometry.
2. Click Insert tabImport panel (Import CAD).
3. In the Import CAD Formats dialog, for Files of type, select one of the following:
   • OBJ Files (*.obj)
   • STL Files (*.stl)

   To import 3D geometry using other file types, see Import a CAD File.

4. Navigate to the folder that contains the file to import, and select the file.
5. Specify the category for the imported geometry.

   The dialog lists the supported categories. Some categories are not supported for imported 3D shapes.

   The assigned category determines behavior for the shape. Choose a category that supports the desired behavior.

   For example, if you want the geometry to define a boundary for a room or space, select a category that is room-bounding, such as Walls, Floors, or Ceilings. The default is Generic Models.

   If you are importing into a family, the category for the imported shape is the same as the category for the family.

6. Specify Positioning and Place At options.

   See Positioning for Imports and Links.

7. Click Open.

The 3D shape is imported into the project or family. Depending on the scale of the geometry, you may need to zoom in or out to see it in the current view.
