Interesting how stairs are measured today

We have a client who is considering modifications to an existing stair.  They want to take it from a straight angular affair to a nicely curving lower section.  I met with the stair company today.  The white discs in the photo are numbered targets that a computer recognizes.  They are scattered around the area.  The red stick with the target on each end is a known length.  With the use of a digital camera, the targets are triangulated as the photos are loaded into the program.  That creates a 3-D image that they use to design the stair.  Over my head but, I’ll show the CAD drawing when I get it.  Pretty cool and extremely accurate.  This same method is used for templating counter tops.  The targets are laid along the wall and cabinet edges with the same triangulation method.
