Overlapping elements do not intersect correctly

Issue description 

When designing with components such as slabs that are offset in height you may notice the elements do not intersect correctly.

Although the components use identical building materials with matching intersection priorities, the overlapping areas display visible cut contour lines that cannot be hidden, resulting in improper visual and structural connections.

Solution

Overlapping elements can only connect correctly when using the Solid Element Operations tool:

1. Go to Design > Solid Element Operations...
2. Add one element (e.g., one slab) as the Operator.
3. Add the other element (e.g., the other slab) as the Target.
4. Select the Subtraction operation and confirm with Execute.
