I have noticed that the NamedPositions do not work in the Layouts view. It seems that what ever the named position the view is created with will stick. I was hoping that it would act similarly to the layerstate manager where you could have a different NamedPosition for each layout. I am trying to create a function where I can move two cut planes and an attached mobile plane. The intent would be to create a Revit like experience with the namedpositions where when I changed the named position it would change my drafting plane with the Mplane and modify the clipping planes to show the relevant level information.
