As I understand the market target is the non-professional home builder. Products for this market are not new and never seemed to be successful. By the other hand, if you try to capture professional (or even semi-professional) market share, the quest is not easy also: Sketchup with a multitude of plugins is hard to beat. Where I see opportunity is on VR software for drones that could make plans/3D models with minor human input. Disclaimer: I'm an architect and not in the US, I might be biased.
