Phasing + Phase Filters

[tonkata]

Am I misunderstanding the Phase Filter?

I would like to model the existing building, demolish a few windows, doors and walls, add the new, and finally create plan/elevations showing the existing + new, and demolition as hatched.

So if I understand this correctly I need two phases, being existing + new, but then need to setup a phase filter that shows the previous phase + new + demo.

Am I on the right track?

Here's a better explination of what I'm trying to achieve.

I start by creating 3x Phases

• Existing
• Demo
• Proposed

 

I then create a new Phase Filter calling it Existing + New + Demo, and set all to override.

In the override settings, I set the following

 I then create 3x separate North Elevation views, and set their correct Phase + Phase Filters (images attached)

So basically what I would like to do is have the Previous + Demo + Proposed all show on the one view, similar to the "Previous + Demo", but the proposed also showing.

Is this possible?

Comments: 

About the phases: "Demo" is not considered a phase in Revit, but an action in the New phase. So basically, you need just the two phases that are already there: existing and new. The demolition stuff can be  shown in views, without having to be a phase.

If you want to show all in a view, (existing, demolition, and new) instead of creating a new phase filter, you could use the "show all" filter, which is already included,

Alfredo_Medina am I missing something here? I switched the Phase Filter on the "Proposed View" to Show All, and nothing happened, any ideas?

Hello tonkata,

As Alfredo said, there is no need for a "Demo" Phase. I'm from an MEP firm, and in order to create the building model as you described (Existing, Demo, and then New), I typically create three Views (as shown below) per floor in order to make the process more efficient.

View Name	Phase	Phase Filter	Purpose
Existing	Existing	Show Complete	Placement of ALL Existing Elements
Demolition	New Construction	Show Previous + Demo	Existing Elements to be marked as Demolished
New Work	New Construction	Show Previous + New	Placement of ALL New Elements

You likely did not see any change between "Existing + New + Demo" and "Show All" because the Wall Category's graphics match that of the "New" Phase Graphic Overrides. If you were to change the Wall Category's lines and patterns to be green, for instance, you'll then see a change by toggling between the Phase Filters.

The difference between these two Filters is that "Existing + New + Demo" shows ALL Elements according to the Phasing Graphic Overrides, whereas the "Show All" Filter will allow the NEW elements to be shown according to their normal settings (typically Object Styles).
