Organizing and filtering elements inside revit model by time

[Anonymous]

Hi, I'm trying to integrate a time parameter inside my revit model so that I can filter the views by the current week of the actual construction. For that I'm creating a "starting week" shared parameter that will be inside every element of my model, something like this: Foundation (starting week = 01); structure (sarting week = 04); brick walls (starting week = 07) and so on. The ideal model would be one where I can tell Revit "show me how the building will be in the 27th week of construction" and the model turns off the view for anything inside the model that has a time value greater than "27th week". For that I think I will be donig various filters, each one reffering to a given week.

Furthermore, I need to be able to account for delays in the construction without having to manualy change each "starting week" parameter inside every element of the model. So, to keep using the example above, if there is a delay in the construction of the structure, the "starting week" value inside the brick wall and every element with a "starting week" value beyond that shoud be: (previously assigned starting week value) + (delay value).

I would be really gratefull if someone could give me some insight on how to go about doing this inside Revit. I heard that I should be working in Navis Works to do this kind of thing, but it really doesn't seems to me like sonething that Revit woudn't be able to do, even if it is more time consuming.

Thanks

I figure that Phasing could solve this problem:

as for instance Phases: -

• Week 01
• Week 02
• ....
• and so on...

[constantin.stroescu]

or you can use Filters.

• select the entities for Week 01 , and save them as Selections - Name it Week 01
• proceed the same with Week 02...
• you can edit these Selection as you want , adding and subtracting entities
• Then in VGO 

The problem with Filters is that this setting is View Dependent , but using Phasing in not and that is the advantage of it..

First thing first, I would not use Phasing for this even though it sounds tempting.

Create a project text parameter, name it Timeline or whatever suits you, and assign it to all applicable categories. Then, you can use this parameter to create filters for views and schedules.

I would be great if Revit supported date/time parameter type, but alas.

With that said, Navisworks is definitely a better tool for this.

Don't use phasing as @ToanDN says. But you can add a project time parameter, but it works with units from seconds to hours (weird restriction really). And unfortunately no date parameter... But you can fill in for a week ie. as formula "=7*24" to calculate that in hours more easily. It is then possible to filter for <xx hours ie. (theoretically, it's not as practical) or in a schedule. Also there are apps out there to do this type of thing for you...

Ah I see they have introduced Time parameter in Revit 2020.
