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.
If you create a plane on one of the surfaces and align to it, then create a point on the other surface when you do a distance dimension you can make sure that the "line" is completely parallel to the 'Z' (or whatever) axis. That should give you a "caliper" result. Also check you are in the correct workplane when doing distance dimensions.
I would also say to check your caliper is reading correct, it has happened to me and a few other people on this forum where you start chasing problems with the CMM and your program when in fact the problem lies with the manual equipment.
