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)

No, it isn't. When you import an object you are required to position it manually. You can't just let Lumion match the origin point.

I meant the origin of the imported object.  Once you place your first object it essentially becomes the world origin and all objects can be aligned to it.

The only time a Lumion origin would be useful to me is with numerical based sun position and if the editable terrain were larger thn 2.5k x 2.5k.  I would like to see a minimum of 8k x 8k since I work with mostly large scale projects.

A larger scale than 2.5 kms would definitely be good. Especially that Lumion seems to be able to handle these scales pretty well (with the LOD engine) so why not?

Okay, I have tested the idea I wrote about above. It can be used but it is not 100% accurate. Now I tested it with planes and a gap in a plane can be ugly but maybe when placing buildings, an 5-10 cm difference in the location would not hurt much. Still of course, some more accurate (and easier) solution would definitely be good.

@Gaieus,

What is the intended result of your experiment?  Are you attempting to manually align the planes to the top of the pyramid?

It was just a forum topic experiment as there was the question how to import and place accurately. I do not have a current project where I'd need this however I can imagine one coming soon so experimenting is always good.
