3 walls connection problem

Zendrix — Tue, 28 Jan 2025 13:51:26 GMT

Hi!

We r working on a rehabilitation project, where the existing building has some skewed stone walls.

We are also making an addition to the existing and here is where i cant solve the problem: we have 3 existing walls that are coming together in one point, and from this point on one of the walls is going to be covered with ceramic tile (brick like ceramic tiles) and the new addition keeps going on a new wall made of brick.

The thing is that the 3rd existing wall where i want to change the surface material is merging/blending with one of the adjacent walls, which throws off my attempt to stop the brick material where i want it to stop.

Any ideas?

P.S. Also there is an invisible pilar element in between 2 of the stone walls, in order to make that werid existing inside corner.

Hi,

You could define the narrower wall to have a different building material, with a higher intersection priority than the thicker one. That way, they will not intersect, but they will overlap.

Assign it a different material (or create a new one), go to options - element attributes - building materials

and raise the priority so that the value will be higher than the other one.

Pro tip: keep the element you want to edit selected so that its building material shows highlighted in the list

Have you tried adjusting the junction order of the walls?

Make the one you don't want to tri less than the other two.

Thanks. ill try that. The thing is that the material is the same and i was trying to not duplicate materials unnecessarily, but i will if i have to! 🙂

Cheers,

Hi Barry!

Im trying to figure out what to you mean by "making it less than the other two". Which less value are you referring to?

In plan is showing it correctly, but in reality (3D) its merging.

Cheers,

By the way, its actually a complex profile, its just that im using Override on that printscreen view i showed to you.

Does that mean i would have to also make the plaster a new material as well(with higher intersection priority) so that it doesnt intersect with the other wall's plaster?

Cheers,

This is the junction order I mean.

When more than two wall join with their reference line at one point, you can control which wall trims to which.

Lowering the junction order of the wall with the door (brick ceramic) compared to the 2 plaster wall (keep them the same junction order) should affect how the walls trim to each other.

Although the complex profile might be complicating matters.

Barry, can't thank you enough!!

That solved it!

Thanks!

Hi Barry! Again on this topic, the wall actually stopped where i wanted and did not go further, but i have now a minor issue: The plaster of the perpendicular wall is not being "sectioned", it has more priority than the stone vs stone, which should stick together. Any ideas?

Thanks,

That would most likely by due to the Building Material Interseciton Priority of the plaster / render being high than that of the stone. Or possibly that you have not properly defined your Core and Finish layers.

Lingwisyer is correct.

The stone building material needs to be stronger than the plaster.

i Barry!

I was able to solve the problem i had when i had a normal wall and reduced the junction order from 8 to 7, as i stated before.

Now i needed to update more info on the wall, so i had to make it a composite wall, which has as a final layer brick masonry. But now when i join them again, i get the initial problem, because being 2 composite walls, i dont have the junction order available.

Any ideas?

Thanks,

Can you select those 3 walls in plan.

Then go to FILE menu > External Content > Save Selection as Module.

Then ZIP the MOD file and attach it to a reply here.

I can then have a look at those exact walls.

Or maybe it is simply this option in the wall settings.

For the vertical wall next to the stairs, you may need to turn this off.

Hey Barry!

I tried the "End surfaces" option, but no success. Its probably some rookie mistake, but i cant figure it out.

i attach the ZIP file.

Thanks.

Thanks for the file.

3 solutions that I can see.

1. Set the brick wall back slightly so face of brickwork does not align with the plaster - you may not want to do that.

2. The plaster building material needs to be stronger than the brick - again you may not want to do this as it will affect the plan a little and is technically not correct.

3. Which is the best solution I think - and I almost had it before.

Select the brick wall and set the 'End Surface Override' on.

I said this before but for the wrong wall.

This seems a bit odd as it is not the end of this wall, but it seems to work.

Are the walls square with each other?

Re: 3 walls connection problem

Barry Kelly — Thu, 20 Feb 2025 06:08:05 GMT

Not quite, but it is working on an existing building, so not a lot can be done about that.

Barry.

Re: 3 walls connection problem

Lingwisyer — Thu, 20 Feb 2025 07:39:41 GMT

That would explain the "end surface", though I would have thought that Junction Order would have resolved it...

Yes, the slight difference of angles (not square or parallel) will create a very thin mitre at the corner.

It is best to always keep things square if possible.

Hi Barry!

Thank you so much for yout input.

Options 1 and 2 dont seem very clean to me, specially changing the intersection priority of plaster higher than a material like brick, so i went with the 3rd option and it worked out great!

Being a renovation and trying to be accurate on all angles makes it impossible to be orthogonal, so a lot of problems like this arise.

Thank you very much,
