To adjust the intersection of elements (or their skins/components), you can do one of the following:
Change Building Material Priority (Affects All Project Elements)
1.Select the element that is problematic.
2.Open the Building Materials dialog box.
3.Select a Building Material, then use the Intersection Priority slider to change the priority.
Note: Any changes you make here will affect all project elements which use that Building Material!
See also Intersection Priority (Building Material).
Duplicate Building Material (Apply to Single Element)
If you want to adjust the priority in just one element of the project, you can create a duplicate Building Material with a different priority.
1.Select the element that is problematic.
2.Open the Building Materials dialog box.
3.Select a Building Material.
4.Click New and make sure you are creating a Duplicate. Give the duplicate Building Material a new name.
5.The new duplicate is selected in the Building Material dialog. Adjust its priority as needed.
6.Assign this new Building Material to the problematic element.
