It is not the expected workflow that you create a Demolished phase and a Temporary phase.
You only need an Existing phase and a New Construction phase. (And additional New Construction phases if your project actually requires them.)
1. You model all the existing in a view that's set to the Existing phase, of course.
2. You have a view set to the New Construction phase, with the Show Previous + Demo filter. You take the little hammer tool and demolish stuff. This view can be named DEMOLITION.
3. You have a view set to the New Construction phase, with the Show Previous + New filter. You model all your new stuff. This view can be named NEW WORK. If you use the hammer to demolish something that is new, then it obviously was temporary and will be overridden appropriately.
4. You have a view set to the New Construction phase, with the Show Complete filter. This view can be called ALL DONE GO HOME.
In other words, each Phase of construction is designed to accommodate demoing some stuff, building some new stuff, and demoing some of that stuff too. You can do a whole building like that.
You want to create another Phase in the project if you're going to go through another round of demo/build/remove later. In which case the COMPLETED state from the previous Phase becomes your "existing" condition for the next Phase.
Make perfect sense?
