My problem is measuring symmetry, at the moment my A_A axis is a line of midpoints at 3.45 (point J) and 21.8 (point H). This is the center of the coordinate system x=0
I built planes from two opposite sides, created a set of them and measured the symmetry, but I got very strong deviations, although the x of this plane is not so bad.
I'm afraid it's an alignment issue, as the part itself is much more complex than what I've shown, but I hope I'm just not measuring the symmetry correctly.
