demolished walls not room bounding when showing demolition

[jonathan5Z9MB]

I'm trying to place rooms on a demo plan. phase filter set to show demolition. phase set to demo. none of the walls being demo'd are bounding rooms. how do you show rooms and show the walls to be demolished at the same time?

Revit only requires two phases, Existing and New, to differentiate between those projects states. In Revit, demolition is an activity that occurs during new construction. Rooms do not travel across phases (like other elements) so a room that belongs to existing must be recreated in the New phase if that room is unchanged between existing and new work.

Use a floor plan assigned to Existing phase and create the existing building elements and rooms

Use a floor plan assigned to New and using Phase Filter Show Previous and Demo (demolition plan) and demolish all the elements (rooms can't be demolished).

Use a floor plan assigned to New and using Phase Filter Show Previous and New (new plan) and draw new design. Place new rooms and copy existing rooms that are unchanged and paste them into the New plan view.

If you have a lot of existing rooms you can "cheat" the demolition plan by creating a floor plan view assigned to the existing phase with all elements turned off except for rooms and room tags. This view can be "stacked" on top of the demolition plan on a sheet allowing you to show existing rooms on top of the demolition plan (which is assigned to the New construction phase).

Another approach aside from overlaying two views in sheet is using a view filter based on phase created/ phase demolished criteria in lieu of phase filter, to override graphics of elements.

For example to create a Demolition view:

- view phase = Existing

- view phase filter = None

- a view filter for demolished elements: override to show as demolished

- a view filter for existing elements: override to show as existing

- a view filter for new elements: hide

Then you can have existing rooms in that view.

if I'm showing a demo plan, and want to have elevation markers on that plan linking to the existing/demo elevations, will that work? I feel like this is overly complicated. Like every project you have an existing/demo plan and then a new plan. You also have existing/demo elevations and sections and new elevations and sections. All of the elevation and section markers have to talk to each other. how is this best accomplished?

Sure, create your elevations in the Demolition plan view. It is assigned to New and phase filter Show Previous and New (stock templates). Views created in this view will inherit the phase and settings of the parent view. Either way you can adjust those settings in a view afterward. You can also "reference other view" which allows you to create a view annotation and "point" to an existing view without generating a new view (assuming you've already set up some views and don't want to make them over).
