3D laser scanners have been around for a while in the commercial sector, creating 3D diagrams for surveyors, but new designs are making them more accessible and easy to use than ever.

A 3D model may be drawn as a 3D diagram. The limitations are the same as the 3D construction model. On a computer it may be possible to rotate this diagram to look at it from different angles.

This would take sometimes hours to complete a basic hand-drawn diagram." The scanner, called the Leica RTC360, provides a digital 3D diagram of a scene, showing measurements and dimensions.
