Slightly OT: Measurement software

[SpazMachine]

You guys are smart and I don't know who else to ask, but I am looking for some software that will take a 2-d outline measured from a plastic extruded part and make a color plot that visually shows wall thickness variations. It seems like a simple thing but I've had no luck finding something.

 

The current way is to sit with calipers and measure a whole bunch of different places and write numbers on a paper drawing. I would like to measure an outline with a CMM (or realistically an ordinary flatbed scanner is probably accurate enough) then have it color in the part with shades of red where it is thicker than nominal and varying shades of blue where it is thinner.

 

It's easy to find something that will compare 3-d models but does anyone know of a way to do it with 2-d outlines?

Ultrasonic thickness gage? Google it, and see what you get.
