“Views Clipped” controls in Rhino 7 seems to have changed from per clipping plane to a blanket all-planes control - see below.
Behaviour in Rhino 6
Behaviour in Rhino 7
Using “Enable Clipping Plane” in a view will enable only the selected clipping plane, but it is impractical to no longer have file-wide control from the modelling viewport. Apologies if this has been posted already, it didn’t seem to appear when I searched.
This is in build 7.4.21067.13001, 2021-03-08
