Creating a backfilled basement

[KittiKorners]

Is there a way to fill in a basement garage (i.e. the garage is on the main floor and underneath is not a room, just backfilled cement) ?   I have a ceiling over it but it still looks like a room in a cross section...Cheers!

Do you want to remove the floor?

[KittiKorners]

Thank you, no, I want to detect that there is not an empty room under the garage but instead basically an 8 foot high slab of concrete...

Do you understand that's not how it would be built?

 

The void would be filled with compacted earth, or more likely, never excavated. 

 

If you want to show a block of concrete, use the slab tool to fill the space.

You are of course absolutely correct; the builder advised me that it would be backfilled with earth. Would there be a way to portray this? I tried building a wall and that seemed to work not too badly but authenticity would be better if possible...

Thanks & cheers!

There is no simple way to model 3D dirt. The software creates surfaces, not solids. A slab, for example is hollow, as seen in the cross section view you provided.

 

That said, you could use a slab (paint with a dirt material) and position your cross section just in front of it.
