This is a straight nozzle lying on the radial plane but the nozzle centerline does not intersect the vessel axis.

(OR1) - Orientation of Nozzle Center Line

The rotation is about the vessel axis and the target arrow is a radial vector parallel to the actual nozzle centerline.

(N2) - Radial Distance to Nozzle Flange

This is an unsigned offset along the positive direction of the radial vector that defined OR1. Refer to the Unsigned Distances section, CASE 3.

(N3) - Radial Distance to Nozzle Center Line

This is a signed offset, the positive being measured along the normal direction of the axes system formed by vessel axis (primary) and nozzle centerline (secondary).

Refer to the Normal Axis section for more information on how to form the normal direction.
