2D polar distance calculation

[[SH...]]

I have two holes in a PCD circle and I have to calculate PCD, but in calypso I can't calculate pcd using two circles so i decided to calculate individual 2d polar distance and multiplied it by two. I measured it as cylinder , the local feature co ordinate of the cylinder from the start point and close to my plane used for 2d polar distance calculation. When I measured 2d polar distance, it gives me wrong result . When I intersect my cylinder with the plane and calculate the polar 2d distance it gives me good results. Cylinders are not allowed for polar 2d distance?. There is only 0.01 difference between my intersection point and cylinder co ordinate value.

You can use recall feature points and choose one of the cylinder scan paths of each one. This will let you use PCD to measure.
