Ok. So I’ve managed to get my pivot lines working. But what I can’t figure out is:
1. How to have a masking fill, so I don’t see what’s underneath the skylight
2. How to have the skylight open in 3D / 3D document / section, but closed in plan (I’ve tried GLOB_CONTEXT and GLOB_VIEW_TYPE, but neither work).

2D Hotspots work just fine though, so it at least executes some 2D commands.

Once again: what is the reasoning behind this?

Thanks in advance.
