I'm measuring the material thickness on a casting with curved surfaces. I have points at the same co-ordinates on opposite sides of the material and am having issues getting the correct readings. The vectors on the opposing points are opposite, not sure if this is correct. Since these are points not along a datum so measuring parallel or perp. to them is not an option. Thanks.
Thanks for all the responses. The readings I was getting were lower than the caliper. I followed the advise given by creating a plane, alignment and everything matched up correctly.
