Hi All

I am struggling with phases in Revit 2014. I have a project where a house was built in the 40's (phase 1), renovated in the 90's (phase 2) and the client wants new additions now (phase 3). So I have created 3 phases.

The problem I have is that the renovations (phase 2) were never drawn up and submitted to the local authorities for approval and council (for some reason unknown reason) do not accept "retrospective" drawings, you have to submit them as though they are new builds. So I have to create 2 drawings of the same building:

1. Drawings for the builder showing what is currently there (phase 2) and what is proposed, with all the relevant demo in the new phase (Phase 3) which is not a problem as I put view into Show all - New Construction (phase 3). Thats easy.
2. The drawings I need to submit to council have to show the existing (phase 1) and the new proposed (phase 3) as if Phase 2 never happened at all. I have no idea how to set this up without "saving as" a completely seperate file and deleting eveything that happened in Phase 2?

Revit seems to show only 2 phases at a time. It takes the "show complete" of the previous phase, turns that into "existing" and layers the new phase over that. So there are walls that were built in phase 2 that are going to be demolished in phase 3 that should be "temporary" (relative from beginning to end) but show as demo and there are walls that were built in phase 2 that need to look like they are being built in phase 3... so I can't even merge the phases because half of phase 2 needs to go backwards and the other half needs to go forwards?

Besides, anything I do for merging phases creates havoc for my drawings for the builders.

Any ideas? Maybe I could use Design Options?

It sounds to me like your phase 1 should really be existing then your phase 2 is the default new renamed as phase 1 and then your added phase 2 which is your phase 3.

So you really only create 1 new phase from revit's standard.   So how do you use this?  ...

1. Draw the exist (your phase 1) and all components on exist phase.  Use a view set to exist and show all.
2. Create a new view set to show previous + new and set to phase 1.  Add your (phase 2) components and demo any exist in this phase.
3. Create a new phase 2.   Create a new view set to show previous + new and set tp phase 2.  Add your ( phase 3) components and demo in this phase anything that needed to be demoed from previous phases.
