About Phases and Linked Models

When you link a Revit model that has more than one phase, phases in the host model automatically map to phases in the linked model.

When this initial mapping occurs, Revit maps phases by matching phase names.

You can manually set up a correspondence between phases in the host model and phases in the linked model. To do this you set up a phase map in the properties of the linked model, and then apply the phase map in the host model.

Note: Phase maps must occur in chronological order. For example, a phase map cannot be set up like the following table. Since phase 1 occurs before phase 3, phase 3 cannot be mapped to phase 1.

Phase	Phase from linked model
Phase 1	Phase 1
Phase 2	Phase 2
Phase 3	Phase 1

Phase mapping is always maintained, unless phases in either the host or linked models are combined. If phases are combined, the existing phase map of the remaining phase is used.
