Alan,

Yes, It can work. CMM's and Digitiser S/W do these types of things
now.

Ideally, you would have the option of DXF or Gcode output.

P.S. A CMM is a Co-ordinate Measuring Machine. Think of it as a VERY
accurate CNC machine that doesn't cut, just measures. Put a machined
part on its' table and touch the probe tip to three points on one
flat side, and the CMM defines the plane represented. Additional
probing will tell how "flat" this side is.

Touch 2 more points (on a second flat side) and the CMM tells you the
angle between the two sides probed.

Or touch the inside of a bored hole in 3 places, and the CMM will
tell you where the center of the bore lies. Additional probing can
tall you how "round" the circle (defined by the bore) is. Neat stuff.
Useful. Expensive.
