Hi Jim,
Right. I have a VE request in for plug-in interaction for floor, slab, roof face, and roof objects. My current need isn't for Marionette objects, but I assume Marionette objects are essentially plug-in objects. The skylight example object is great, but if it can only cut slab objects than it's use (as far as hole cutting is concerned) is limited to flat roofs modeled using slab objects. Id love to see symbol and plug-in interaction with these objects on par with how they interact with walls.
