Me again, to report a bug or something that could be improved with the plugin.
Right now, if you set Z elevation in a 3DObject Properties, it is not displayed correctly in Constructs editor preview window.
For example, I created a 3DShape object (the grey slope) as I use for topology purposes.
Set it's Common properties Z elevation to 32
Then I created a 3D model of stairs, set it's properties Z elevation to 32, yet in preview, the 3DSHAPE renders at 32, the stairs still renders at 0.
In game it works fine, stairs AND grey topology slope are rendered at 32.
But for a level building point of view it could be complicated if every 3D object is not rendered at the right Z elevation in editor. It's working in the dark.
One idea could be to move the Z elevation setting from Properties to Common so it gets rendered correctly.
Else maybe there's a way for the editor to render it at the correct z elevation without moving the setting. Don't know.
