I guess with my ultimate plan was I had bought the Structure sensor so I can scan properties I work for investment company and we buy homes remodel and approve them so for me the Structure sensor was to be able to get a quick scan of a home in essentially have blueprints without having to hire an architect to map it out yes I can do that myself but being the builder and the planter my plate is pretty full so I was planner I was looking for something to speed the process along
