The hub of this elbow nozzle is radial to the vessel axis.
(OR1) - Orientation of Hub Center Line
The rotation axis for this angle is the vessel primary.
(OR2) - Orientation of Flange Center Line
The rotation axis for this angle is the hub centerline and is measured from the vessel axis.
(N3) - Radial Distance to Flange Center Line
This input is unsigned and is assumed to be in the direction of the hub centerline. Refer to the Unsigned Distances section, CASE 3.
