I think this one is so obvious, perhaps I might be missing it. Could you add a few more parameters to library objects so you can select an alternate linetype and pen when MVO is set to Reflected Ceiling Plan view? With all the detail level options now available depending on MVO, I'm surprised this isn't available. I give this capability to almost every GDL object I make for our office. Many of the objects I make are simple wrappers around GS objects so that I can add this functionality.
For primitive elements, I have added a property which I can then access via Graphic Override Rules to change linotypes when I select an RCP Graphic Override Combination.
Related: When I first learned about the cutting plane settings (maybe they were added around AC15 or so??), I had thought a slab positioned above my cutting plane, with proper settings, could appear dashed. And then when looking at the same slab in RCP mode, it could appear solid. Would be nice.
