Intersection Issues

[Anonymous]

Hello, I'm having a bit of a problem with AC17 and wall intersections.

I have set on both walls the exterior skin as finish and the interior as core. It only has a problem in one situation (with red circle) I wanted it to stop before the exterior skin.

Is there anything I can do to solve this?

Thanks

Hi, you can watch this video and say if it did the trick - https://www.youtube.com/watch?v=E_g9r3PELO0

Maybe I'm not getting how this works, but the finish on both sides of the wall (plaster) is the same. I can't make plaster higher priority than the brick core otherwise brick will stop at the plaster right?

Paste here the settings you use for all the materials from the building material's menu and give colour screen shot of the problem.

020_1 is your skin right? Give it intersection priority of 610.

If I do that, no core will intersect correctly:

Hi.
While it is always a good practice to give the wall core the highest priority -so you don't have issues- and work outward from there giving the outer skins less priority, in the case of external finishes, it is advised to have two different plaster materials, giving the outer one a bigger priority -maybe even higher than the core- so that other skins won't cut it.

As for insulation and air-spaces inside walls, while you would think they would need a lesser priority (as in insulation is less strong than concrete, right?) you would want it to have a bigger number so that it is a continuos skin.

Hope that makes sense.

Best regards.

Try making two different materials for inside and outside of the building. So no core can get trough the outside one but the inner intersect correctly
