Yes, correct!
It is probably because you didn’t give the floor some thickness before outlining the walls…

Look around you and compare what you see to what you model in SketchUp:
- your TV is a real object, so also a SketchUp object, a component or a group if you like.
- the painting on the wall is an object, so a component, blablabla
- the wall to your left is …
- the floor you stand on is …
etc.
Of course you can decide that you want all your walls to be in one and the same group or component.
You can work with nested groups and/or components, too. Like you TV that has multiple parts (components) making up the top level object called TV.
Once you have groups and components, only then you decide to have them tagged (asign layers/tags to them) to controle visibility, (some tags on, others off etc.)

No, I did not do that. Yeah, this is a long term project I started a long time ago and did not know to do that. Existing house add on. But I totally see that I should have drawn the slab!
What a great tool this is once you figure it out.

Thank you Wo3Dan!
What a great community here!
I’ll guess that if you go underneath and look up, the walls are hollow - that is, no bottom face to the wall parts. That happens when you when you mix wall faces and floor faces in the same group of raw geometry and start push-pulling them.
My practices of my workflows when doing modelling is,
After i imported my floor plan, and all my faces are completed drawing, i started to create and plan ahead to do Tags for respective layers such as Wall, floor , ceiling, 2D object, 3d objects…etc. and I assigned them respectively.
So, it saved me a lot of time and i do not have to going back to do tags after pulled to 3D.
Just sharing my easy way of doing.
