display ONLY demolished parts of floors

[vojtech.zufnicek]

How do I display ONLY demolished structures?
In the current construction, I have floors, with slopes and different nooks, bordered by walls, various plinths protrude from the floor. Part of the space will be demolished and new structures will be created there. I use only two phases - existing and new. Some elements are demolished whole (demolition phase set to "new state"), some parts of the floor is cutted through the void family. Phases work, show existing + demolished is displayed correctly, show existing + new too, show only new I see correctly too .

But I need to show JUST demolished elements, hide everything else. And this is where I came across it strangely. The element that is completely demolished is displayed correctly (wall, floor, beam, whatever). But if I'm demolishing only part of the element by the void family, that's the problem. The demolished part of the wall is still displayed correctly. But not the floor. I can't see the demolished part of the floor. Even if the wall and the floor are trimmed by the same void family, the relevant part of the wall will appear in the "cut only" view, but the floor will not.
this is what it looks like Existing + Demolition, that's fine

existing + demolished

but only the Demolition phase turns out like this:

just demolished - floor cuts missing

So no cutouts in the floor are visible.

What am I doing wrong so that the cutouts in the floors don't show up ??

Create a new filter phase:

New: Not displayed

Existing: Not displayed

Demolished: By category or Overriden (the visualization that you want)

Temporal: Not displayed

Then turn your phase in the viewport to Demolished

Why not just do this via a rule-based filter applied to the View?  Or are you also interested in using Phase Graphic Overrides?  I mean, it seems this would be unnecessary since nothing else is displayed in the View.

Thats exactly what i did, and thats the point. Floors, walls, beams which was demolished whole (their "Phase Demolished" set to "New Construction" appears on that view. But when i cut part of model with void family, i see cutted parts of walls, but not the cuts of floors and beams, even they are cutted with one void family.

I want to have view with ONLY demolished elements, now i see only some of them 😞

(I want to avoid workaround with dividing the elements one by one to different parts which will be demolished whole).

Forget about Phase Filters. Just isolate the elements you want to show in the View and, if you want them to display differently, Override Graphics in View By Element or By Category or By Filter.  Bada Bing!  No?

For floors, roofs, ceilings, you need to separate existing to remain and existing to be demolished as different elements.
