Z Plane fighting on section plane fills

[KeeneArchitecture]

Help!

Im in sketchup 2026 and ive made a section cut and am using a section fill. We are testing with just one single section cut on a house. There seems to be z fighting happening between objects that are being cut by the same section and I cant see my structural members on some, not all, of my sections (these sections share the same styles, tag, etc).

If i rotate my view to see the perspective of this section, i can see the linework of my structure blinking and fighting with the section of my floor.

Here is a picture of the beam with section fill and no section fill.

In most cases sharing the file is the only way to get help, otherwise most of use here will be guessing.

To start guessing - is the section cut placed right where other geometry might have a plane?

Is the ‘floor’ just a box? If it is it will fill solid and you won’t be able to see the joists / etc.
