DEFINITION OF PHASING •Phase represents a fixed period of time in a project.

•Phase is a view property. Each model view, including schedules, belongs to a phase.

•The phase filter property of each view controls which phase or phases appear in the view.

•Phasing in Revit Architecture, displays model elements belonging to different phases with different line types.

•You can control the appearance of a model by applying graphic overrides to phases. This helps display different combinations of phases in one view according to project requirements.

Each view has a phase & a phase filter.

•This method allows us to display how our project appears during various stages of the works.

•Some Companies have used Phases to construct buildings level by level……

PROJECT PHASES In the default Template file, the phasing dialogue box is located in the ‘Settings’ menu, under Phases.

• Two default phases –Existing & New construction. As mentioned the more complex a project the more Phases are required.

•If project has stages, it is better to create as many phases (or more) as they can be combined with previous or next.

•Demolition is not a separate phase, it is done as part of the ‘New Construction’ phase, Future currently being modeled on.

•Every element must be assigned to a creation Phase, but the Phase Demolished parameter can be set to “None.”

•In other words, all elements must be created at some point in time, but they may or may not be demolished during the life of the project.

GRAPHIC OVERRIDE •There are four conditions (Phase Status) that can be used to describe (and graphically convey)an element at any point in time.

•These are built into the software. You can edit their characteristics but you cannot add or delete them.

•The Graphic Overrides tab of the Phasing dialog shows the four Phase Status conditions and each is described here.

Existing—Relative to the currently active Phase, items created in an earlier phase are considered Existing.

New—Items created in the current Phase are considered New. Demolished—Items created in an earlier Phase and demolished in the current Phase are considered Demolished.

Temporary—This designation is used for items that are both created and demolished within the same Phase.

PHASE FILTERS AND VIEW PROPERTIES •Each project view is assigned a Phase in its Element Properties and can also have a Phase Filter.

•A plan view is assigned the Existing Phase, all elements drawn in that view will automatically inherit this setting and become existing elements.

•We can override the setting by editing the element’s properties, but working with the currently active view Phase can be a much more efficient way to work.

•It is often desirable to create a view for each major Phase of work and then simply make the appropriate view active before drawings any objects.

•Phase Filters work with the settings on the Graphic Overrides tab (of the Phases dialog) to determine how to display each Phase in a given view in your project.

•The default Phase Filter called “Show All” is the only required Phase Filter and also the only one that you cannot edit or delete.

WORKING WITH PHASING 1. Create three Walls in Level 1. Add a Door or Window to one of the Walls.

2. Select one of the Walls, edit its Properties and change the Phase created to Existing. Notice that the Wall you just added is now halftone gray and its line weight is lighter. (Review the Phase Filter and Graphic Overrides tabs above to see why— remember; the current Phase in the Level 1 plan view is New Construction).

3.On the toolbar, click the Demolish tool. Click the existing Wall. Notice that it now turns dashed. Edit the properties of this Wall. Notice that the Phase Demolished property is now set to New Construction.

4.Use the Demolish tool again on a different Wall (the one without the Door).Notice that this Wall now appears dashed, blue and has a hatch pattern within it. This indicates that it is now “temporary construction.� If you edit the Properties of this Wall, you will see that this Wall is created and demolished in the New Construction Phase.

5. Demolish the final Wall. Notice that the Door is also demolished. You cannot demolish a host without also demolishing its inserts. Revit therefore does this automatically.

6. Undo the last change to return the Door and Wall to New Construction. Select all three Walls and the Door, edit their Properties and change their Phase to Existing and their Phase Demolished to None. Everything should now be halftone gray and solid lines.

7. Add a Door to one of the Walls. Notice that Revit automatically demolishes a portion of the Wall to accommodate the new Door. Use the Demolish tool and demolish the existing Door (the one we created above). Notice that Revit automatically fills the hole with a new segment of Wall.

8. If you want to demolish a portion of an existing Wall, use the Split tool to break the Wall into segments and then demolish the portion required.

9. To see the final result of all edits, edit the View Properties of the Level 1 floor plan.

Change the Phase Filter to Show Complete.
