I been reading about WalkAbout3d (http://www.walkabout3d.com/) for Sketchup and have seen a couple of videos of walking around the outside of a house and a park.
Does anyone know if WalkAbout3d also allow the user to "walk" inside a house/building such as the introductory video they have on the program 'Grand Designs' where you visit room to room of the house in question?
