Use phase properties to assign building model elements to specific phases. You can also assign copies of views to different phases and phase filters.
Phase Properties for Views
Each view in
Revit LT has a Phase property and a Phase Filter property.
- The Phase property is the name of the view phase. When a view is opened or created, it automatically has a Phase value. You can copy a view and then select a different phase value for that view. For example, the original view has Phase 1; the copy has Phase 2. You create an element in Phase 1 and demolish it in Phase 2. The element displays as new in the original and as demolished in the copy.
- The Phase Filter property lets you control the display of elements in a view. For example, demolished walls may display in blue dashed lines, while existing elements display in solid black lines. You can apply a phase filter to a view to see elements from one or more specified phases.
Phase Properties for Elements
Each element that you add to a project has a Phase Created property and a Phase Demolished property.
- The Phase Created property identifies the phase in which the element was added to the building model. The default value for this property is the same as the Phase value for the current view. You can specify a different value as needed.
- The Phase Demolished property identifies the phase in which the element was demolished. The default value is None. When you demolish an element, this property updates to the current phase of the view in which you demolished the element. You can also demolish an element by setting the Phase Demolished property to a different value.
- Both Phase Created and Phase Demolished properties can be used in view filters. See:
View Filters
Phase Status
The phase of the view and the phase created/phase demolished properties of an element work in conjunction to establish the phase status of the element in a view. The phase status of an element is used by the phase filter of the view to establish visibility settings.
- New - Phase Created of the element matches the phase of the view.
- Existing - Phase Created of the element is from a previous point in the time line than the phase of the view.
- Demolished - Phase Created of the element is from a previous point in the time line and also has a Phase Demolished property matching the phase of the view.
- Temporary - Phase Created and Phase Demolished of the element both match the phase of the view.
