Playing PCB Tetrix

[JTEX]

Does anyone know what is the right way (or if there even is a proper way...) to display two boards at the same time in the 3D viewer to check for fit? (one of them plugs into the other). So far the only way I managed to do something like this is to save one board as a STEP file and load it as a component onto the other board. Pretty clunky IMO, and it takes way too much work to move them relative to each other.

Here, the bottom board is a STEP file while the top board is the actual PCB loaded in the Kicad project:

I’m guessing @Robert and @dan.schumaker have both done this plenty of times before and may be able to assist!

I'm not using the most recent version of KiCad, but this is more or less how I do things when I need to check fitment on stacked boards.

There is a plugin for FreeCAD that some folks use called KiCad StepUp which exports boards to render stacked mockups. I've tried going this route but the interface isn't the best.
