So i deal with alot of symmetries on my parts.
Alot of parts looks like an " H " where the inner (midplane) is supposed to be symmetric with the outer (midplane).
I measure all 4 planes. Construct a midplane for the outer planes (in X+ workplane). I define this as reference A
Then i measure the inner planes and construct a midplane for these and evalute the symmetry against reference A.
I get around 0.06mm from nominal ( nominal is 0)
But if i measure the distance between the midplane the result is only 0.003mm from nominal.
Whys this?
