Open an existing model, and link another model to it.
You will link another model into this model.
In most cases, you should select Auto - Origin to Origin.
If the current model uses shared coordinates, select Auto - By Shared Coordinates. See Shared positioning.
If you cannot see the linked model in the drawing area, do the following:
This setting ensures that the view displays elements for all disciplines (architectural, structural, mechanical, and electrical).
You can select the linked model in a view and drag, copy, paste, move, and rotate it.
Both the Project Base Point and Survey Point from the linked model are visible to help you align coordinate systems between models.
When you link a Revit file to your model using Link Revit, the grids from the linked file are not visible in the current model.
You can also monitor levels and other essential elements in the linked model. See Multi-Discipline Coordination.
