Wall intersection in AC17

[Anonymous]

Hi All,

In version 15 we resolved this intersection issue below by turning off the wall priority and had no drama.

We have now upgraded to v17 and its seems the wall priority has been replaced. I tried using the Junction order, however it didnt work.

Any ideas or can anyone link me to a solution ?

G'day Heath,
The wall priorities are still there - just a little different.
The skin strength is controlled in the Building Materials now.
You can't simply turn off the old "Enable wall skins" button in the wall properties anymore.
I believe the Junction Order you mention comes into play when to walls have identical properties.

Or your problem is the walls are in layers with different priority numbers - different layer numbers still won't trim as before.

Hey Barry,

Yep I see the priority section now. I shall have to make changes to my template. thanks for that

The new Building Materials (and their priority strength) now apply to all composites - walls, slabs and roofs.
Wall/slab junctions in section/3D will now be automatic (so long as "Legacy" mode is turned off in the options > project preferences > construction elements - otherwise junctions will be as they were in 16.

So your concrete BM for the floor slab will need to be stronger than the brick BM for the wall and the plaster BM on the wall will need to be stronger than the floor covering BM.
If a wall is made from a concrete BM and a slab has the same concrete BM then they will blend in section.
If you don't want that to happen you will need to create a wall concrete BM and a separate slab concrete BM with different strength depending on which one you want to dominate.

It does require a bit of thought but you now have 1-999 for the strength values and you can drag a material up or down in the BM dialogue (when sorted by strength) and the strength will adjust automatically to be weaker than the material above it but stronger than the material below it.
