Typically, in FlightSim LOD, the closer you are to an object, the more polygons. I get the impression that Architectural LOD idea does not assume a monotonic increase in polygon count as you get closer to the object. However, it seems that Architectural LOD is a way of packaging the idea that you will have many drawings for many different purposes, perhaps corresponding to different people doing the viewing. For example, the electrician doesn't care about the shrubbery. On the other hand, the customer probably wants a walkthrough, and that seems likely to be implemented using FlightSim LOD. Right?
