Will walls intersect walls in section?

[Anonymous]

I cant seem to get wall-to-wall intersection priorities to work in section view like below where I want to have the plywood and shingles come down below the concrete.

In plan wall to wall will only work if the reference lines intersect it seems and I dont know if this effects how they behave in sections

Floors -walls seem to always work without having to line up edges or reference lines at all

You can also check that the Wall and Slab layers have the same intersection group numbers - if they are different then they will not collide.

That was it thank you! Missed that one.

Thank you James for your help previously. I am still having difficulty. The priority based connections are not cleaning up consistently.

The second floor slab with first and second floor walls clean up nicely (see attached). The first floor slab, first floor wall and foundation show a projection of the floor slab through the higher building material priority of the concrete foundation.(see attached)

I have no overrides selected in my model display options, no cut surface overrides in the wall plan/section display, no overrides in the renovation filter either. The intersection numbers in the layer set are all the same.

Here is a screen shot of the same model where the walls and floor clean up correctly

When the intersection occurs, can you select the Complex Profile and show selection in 3D. There are fills I can see in the Profile that don't have edges which is currently not possible.

Also, if the Complex Profile a Wall or Beam? (not that it should make a difference)

The foundation is a complex profile wall, it includes a fill used to create an airspace.

Here is a screenshot of the walls and floor together

I still don't quite understand how your model is made up.

Try intersecting a beam through this Complex Profile (in an X intersection), and check the resulting Profile after the collision.

Try with another simple Slab (non-composite) and intersect with the Profile, and check the resulting Profile.

To check the intersection priorities of each of the skins, try selecting both the Profile and the colliding element then open the Building Materials dialogue - it will highlight the selected in the list.

Again, check if the Layers are the same. And check that they both have the same Renovation status.

I double checked my settings and this was my oversight yet again! The complex wall in question was on a different layer with the wrong intersection number, the problem is now corrected. Thank you again for looking at this.
