Clean up junctions in composite walls

Paul King — Tue, 30 May 2023 10:47:02 GMT

Hi - I am really struggling with wall clean up behaviour with two dissimilar composite walls.
These need to clean up and show a stop end to one layer of one composite while, and clean up junction of another layer of composite without changing the overall wall shape - all these things needing to occur in the same place.

See screenshot of raw walls (top) and fills I have used to show the desired cleaned up result (bottom)

I want to avoid messy workarounds involving custom discrete polygon wall objects, 2D patches etc.

I tried using the wall end tool for stopend of brick outer leaf of composite, but find in general that wall end tool fails (messy extra/missing lines etc) when end of wall is also attempting to clean up with another intersecting wall in same place.

Can anyone show me an elegant way to achive what I need here?

The last time I had such a problem I took the problematic intersection, created a Custom Profile of it and assigned it to a Column. Then placed the Column into the intersection. The good thing is that since the fills are the same they blend nicely. Also the Column cuts itself out of the Walls automatically. Worked for me.
This is better than trying to use a polygonal Wall because you would have to use several polygonal walls since there are several skins involved.

Thanks - close, but not quite - the end of grey inner leaf/wall intersects in a different position - strikes a corner, not just an edge. Also does not give return/stop end to outer brick leaf

Thanks, that worked!.

Still a pain that workarounds like this needed with composites. They need to be smarter and allow each leaf to extend & clean up in independent ways - like separate walls, except for sharing common openings for doors & windows & dragging around together as one grouped item (guess this must have been wished for many times over the years!)

You are missing the small section of wall that is perpendicular to the end of the multi-skinned composite.
