Hi,
We are using Model Visibility (“Model On” in the layer panel) to turn on/off layers in the model space.
Unfortunately we do not manage to get expected behaviour when using Layer States to restore model visibility. Here are the steps to reproduce the problem:
-1/ Switch “model on” in the following way, turning off “A” layer only. Sub layers are hidden but would still be visible if “A” was turned on again. We see the half electric bulb diagram.

-2/ Save a new layer state and restore it. This damages the layer visibility by turning off all sub layers of “A”.

I guess this is a bug, unless it was intended but i don’t see why…
