minimum thickness measuring

[[st...]]

hi,

so we had this request to measure the minimum wall thickness between a hole and a plane
my initial idea is 'this is pretty straight forward" but it turns out it isn't what i thought

anyone can point me in a correct way to measure this

added a picture to explain it better, i need to know the minium thickness of "B"

You could be use the Caliper Distance like that:
Circle or cylinder with minimum on top and plan A with center on the second element.

Create an alignment with the two side planes not being measured (Symmetry - Spatial) - (circle XY origin) - (top plane Z origin). Then in the Caliper distance right click in each plane field chose evaluation > outer tangential & inner tangential. These will give
you the max (high points) and min (low points) distance respectively. If you need that kind of accuracy? Otherwise just use LSQ.
I'm not sure if choosing min or max for the plane inside of Caliper distance will do the same thing. It might?

I might be missing something but the simplest thing would be to scan three circles. Top, middle and bottom. Then do caliper distance from that A wall to the minimum of each circle. Now you have the thickness throughout the whole piece.

You also might want to try creating a secondary alignment where the bore(Cylinder) is used in rotation in space. Then pick that secondary alignment when using caliper distance. Just to verify there is no big difference.
