I believe you need to build a ground plane or "solid" (meaning closed-faced volume, but not necessarily a true solid) to keep your objects from sinking due to "gravity". I do not use SP, so I am not sure of some of the terms, but the ground plane "attributes" may have to be "static". Then, your rectilinear object should rest on the ground, unless you grab it or push it or elevate it. There are others here who use SP, who can answer your questions better. I just thought you needed at least a reply, and maybe my comment can help you along.
EDIT: Have you checked some of the tutorials on YouTube?--and I mean some of the basic ones. A couple of them are both informing and amusing.
I take the slow, deliberate approach in my aimless wandering.
