PBC and Door/Window Issue

[Anonymous]

Hi Folks,

I'm facing an inconsistensy within the PBC (Priority Based Connection) concept...
- I have a door opening on a wall based under the finish floor;
- My floor finish cross this door.

The logic behavior would dictate that if the floor was crossing air... it would't be interrupted right?

I know I can change the layer to a different priority number an have the continuous floor, but this would give me an incorrect floor area.

I could also set the floor BM to be stronger... same scheduling issue.

For me, the only correct solution for this would be to create a separate wall just for the door and elevate its base... And this just don't make any sense for me.

So I'd like to know how you deal with PBC crossing Doors or Windows?

Cheers,

Paulo

If a door touches a slab and the part of the slab it touches is setup as 'Finish' it will extend that part of the slab through the opening.

You nailed it Erwin!

I was using a single layer composite for the floor. So I created a transparent layer below to match/flush the wall base and its ok now.

Thanks a lot!

Cheers,
Paulo

Edit: And thank you Luca! You were right too.

You actually didn't have to add transparent layer below - one can create single layered composite structures (I've heard it is actually good practise, not sure why though, besides the cut pen control).
Just keep in mind to set layer type to Finish/Other to extend slab into a door opening.

I know I'm bringing back old topic, but perhaps someone will find that info useful.

Hi Luca,

Indeed single "finish" composite cover the opening space.
But the issue I was facing was more complex than that.
It was not only the top layer of the flooring. The empty space below the floor was not covering the opening space.
In the double skin composite, both are set to "finish".
