Phasing

[Anonymous]

Hi,

I'm working on a project where we are semi demolishing an existing building, and putting some new structure back in. I would like to use 6 different phases to show how we demolish and reinstate new structure. The building is 6 storeys high and the new structure will have to go in sequentially from the bottom up.

I am using phasing and have cut some sections at key locations trhough the project. I would like to show all of the existing as grey (as revit does by default). My problem is however when I go from phase 1 to phase 2, all of the new structure that I put in at phase 1 goes grey and look identical to all of the retained existing structure. I would like to show new structure that was constucted in a previous phase as "by category".

How can I achieve this?

Cheers,

Matt

I'm imagining you want to have a "Show Complete" type view, but where each phase is represented by a different line pattern or fill pattern perhaps?

I don't think view filters allow us to filter by phase. So my idea is to duplicate the steel material. Make a "Ph1Stl," a "Ph2Stl," etc. Give these materials each a different surface or cut pattern as required. Now select all your phase-1 steel and swap it's material to Ph1Stl. Change your other phases appropriately.

This seems like a dumb work-around. We ought to be able to filter by phase in view filters. But maybe it will work for you?

If an element belongs to a Phase previous to the current, it will be under the "Existing" effect of the View's Phase Filter. There is no way to differentiate the existing elements' actual Phases; Revit will treat all past elements as "Existing".

The method I would recommend would be to either place the "Existing to be Retained" elements on a designated Workset and then create a View Filter with Filter Rules that target that specific Workset. Add this View Filter to the appropriate Views or View Templates and configure the desired appearance. Then, you can modify your View Filter to display the "Existing" elements "By Category".

I have a question, though. If you are showing the previous Phase's structural work "By Category", how will it be distinguishable from the current Phase's structural work?

Chris,

Thanks for your reply. I need to show each phase the same, in that anything new
for that particular phase shows up blue, anything created in a previous phase as
"by category" and anything that is there prior to demo as grey, so I don't
really want to have lots of different materials. Besides, I have got concrete
floors and precast concrete beams to consider as well, so this will create a
myriad of materials, not to mention problems with joining etc.

Thanks for your suggestion though.

Thanks for your suggestion. I've created a new phase filter and changed the
overrides to show all new elements as blue, with a light blue shade.

I will try your suggestion of putting all of the original elements on an
"existing" workset, and filter each view to show the existing elements grey,
similar to the phase manager dictates.

Will the filter override override the phase override?

Just to add to the option, if you do not wish to create a Workset, you could just as easily add a Yes/No or Text Project Parameter, and then reference that in the Filter Rules. Either way, you will still have to address each existing element (by placing it on the Workset or by setting the value of this Project Parameter).

Yes. Aside from overriding "By Element", View Filters are the most predominant override.
