Auto Features not moving...

Not sure of it, but are you sure of "spacer=0" ????

i think thats only with regard to a feature other than a plane circle.

It's been zero from the beginning and its not an issue on the other features.

whats happened is they machined this tip then heat straightened if for true position. thus the grooves are not perpendicular to the long axis of the part. when the program tries to probe the circle path of the slots (measuring the distance between them) the probe contacts the edge of the slot as it approaches it and stops the program. I'm trying to give the circle path the same X and Z center as the OD of the part (CYL181) and the IJK of the plane at the right side of the tip (PLN_512).

the problem seems to be that the program doesnt recognize any of these changes.

I've even reverted to the unmodified XYZ and IJK targets of the original program and just given the Y value a different number, in one case 2 inches shorter than the original number, and the probe still looks for the plane at the original location and crashes (slowly) as it approaches the slot.

odd... i can't figure out why the target Y doesnt seem to see any of the changes I'm trying to make
