BIM, building information modeling. To simplify, CAD is dumb and BIM is smart. While CAD software has been expanded to include some smart features and 3D tools, it is largely a facsimile of paper and pencil. Lines are just lines, they don’t know that they are supposed to be a thing that is part of something. BIM uses 3D models to generate the drawings that compose the “blueprints” but there is information associated with what you see, it knows there are walls, floors, roofs, doors, light fixtures, and so on and so forth. Since it’s a 3D model it can also be rendered and is then publicized as “concept art” that isn’t actually conceptual.
If you remember back to New Fantasyland there were videos showing off how they were using 3D models for coordination, that was BIM. This document also shows some of the differences:
