Sketchup Layout & Section Planes

Hello!

This may be a silly question,

When I create scenes in Sketchup, I use section planes since my model is closed in.
When transferring them to layout, the scene does not keep the section plane because I am creating multiple scenes for different areas. If that makes sense.

How can I stop this from happening?

Thanks!

It would help if you share your LayOut file so we can see what you are seeing.
