I have read many places that one can set the visibility of layers specifically to each detail view in a given layout by double-clicking the view so it is selected, and then make changes to the visibility in the layers panel.
However, I have tried this a zillion times and all details are affected.
What am I doing wrong?
Ok. So the steps to achieve this are to select the detail view, then use the “Detail On” lightbulb by the layer you want to turn on/off. Makes sense, but I have never seen that mentioned.
Yep, and you can choose to reorder the columns, so the lightbulb, you wish to switch on/off is closer to the left. In Rhino 8 it is also possible to set a layer to be visible in ALL of the DetailViews in LayoutSpace but NOT in the Modelspace. That has not been possible in previous versions of Rhino.
