Strange thing, but in API there is a declaration of a enum FBViewerMode with enumeration of a pane layout and schematic view… but I’ve lost to find a function which can take that enum as argument and change pane layout in a viewer. Is that mysteriuos function exists or not ?!
P.S. I have found a way how to determine if schematic view is switched on
Property CameraViewportX of a current camera got a value -4 (I’m checking for any negative value)
