I'm not sure that I'll be able to use phasing, although I think the options could be changed a bit to allow it, but for now I don't think it's possible.
the problem, as I see it, is that I have the two scenarios, tenant & shell, but they are essentially constructed at the same time and only are shown different for pricing purposes. There is also existing work that will remain (duct mains, piping mains, some equipment) that both the new tenant and new shell work will connect to. I could use a different phase for each and then use graphic overrides to control the appearance of each in relation to each other. But, Revit wants to treat the different phases in sequence, so when I'm looking to control whatever I've called the last phase whether it is new construction, or phase 2 or whatever, all the other previous phases then show as "existing" when only what I've labeled existing should be shown that way. If the graphic override included options for controlling the visibility of each phase that was created that could help, or maybe there is a way.
Also, the graphic override is basically set for the entire project and would need to switch when printing between the two scenarios. Not sure if this makes any sense at all (it's really confusing the hell out of me) but I'm just not seeing it being done with the phase filters.
Also, what is done with tags in phasing? they don't have a default phase selection so they seem to show the same regardless of which phase...which definitely doesn't make much sense so I may be WAY off on that one.
Thanks,
Mike
