Specify the Linked Model as Room-Bounding

You must activate the Room Bounding type property on the linked model itself to be able to place spaces in a linked model.

1. If you do not already have a linked model, use the instructions in Link One Model to Another to link models.
2. In a plan view of the host model, select the linked model.

   The status bar displays the following:

   RVT Links: Linked Revit Model: <model name>.

3. In the Properties palette, click (Type Properties).
4. In the Type Properties dialog, select Room Bounding (it is deselected by default).
5. Click OK.

Note: You cannot use IFC-based curtain elements to define rooms. If needed, add room separation lines along their boundaries. See Add a Room Separation Line.
