There could be a way (have not fully tested it yet). I made this small pyramid right in the origin in SketchUp. Its base is 1m x 1m but what is more important is that its height is 1m. Now when you place anything in Lumion on top of another object, it will report how high you are placing it. Now when you see the 1.0 (metre) height in Lumion, it must be right in that very spot on the horizontal plane, too. Use this small, reference geometry to place anything "on top". Each new piece of geometry only needs to have its own origin precisely aligned with this one, single spot in your modelling app.
(I need to escort wife "pubtown" now but will be back with some real tests later)
