Composite Wall intersection problem

coty — Tue, 09 May 2023 12:19:50 GMT

Hi everyone,

I hope someone can help me. I have a wall with two corners. On one side is simple corner and on the other side is 3 walls intersecting. All walls are the same composite wall, The reference line on the outside face, same junction order, same overall parameters. I am posting pictures with the problems.

When I use the intersection botton this is what happens:

Any Ideas why this could happen?

Hello @coty

It seem to be because of another wall below or above this one. Did you check these walls through a 3D view or a section ?

Select the wall & check BM priorities if the composite edge is higher than the block skin make it lower to enable correct intersecting.

Hi @Christophe Fortineau
Yes I checked. I actually extended the height of the wall under (that is not the best solution) but it worked

@Mahmoud Qenawi The priority of the block is higher so I dont think this was the problem. But thanks.

Sometimes that happens cuz different heights for walls or different home storeys.

@coty

You seem to be using a composite wall which includes various materials. You need to consider all the materials in this composite wall. On the contrary, I think that the interaction between these two walls is the cause of your technical concerns and that the various materials of your composite walls deserve greater attention. Can you share a small file that only includes your walls ?

So now this is what I did:

I extended the wall from under

And this is what happened: What I wanted to fix I fixed it but came out with other problem

Do you have to extend it to double height?

In this case I would extend the lower wall only to cover the RC slab and better create another wall belongs to the story above to avoid intersection problems.

@Christophe Fortineau @Is there a way to share it to you and not post it online? even if it is only the walls. it is not a project of mine.

Hello @coty ,

I have read the solution just above but I ready to open your project file if you send me a downloadable link by a private message for example.

I am not Christophe, but use a file sharing website (there are many).

Then Private Message Christophe (just click on his name to send a message) and send him the link.

You have multiple walls from different stories shown on your single plan? Are you able to set the walls to "Home Story Only"? Are you trying to insersect a multistory wall with a single story wall? Having multiple overlapping walls intersecting with each other will almost always mess up the intersection...
