Concrete garage floor

[steve_d]

Probably just my inexperience, but I got the concrete floor in place today by making sure I was on the foundation plan (floor 0) when I double-clicked to open the room properties. From there, I could choose a material (concrete was already the default).

I'm not sure how I was even able to name the room when I was on the floor 1 plan, because today it won't let me. I suppose it makes some kind of sense to have the garage floor be part of the foundation plan, because it is at a lower level than the main floor.
