Answer: From AutoPIPE online help:
Insert RingAutoPIPE supports the insertion of ring mains into the piping model through the use of the Ring Main Wizard. The Insert Ring dialog is a two-step wizard. The first page of the wizard contains general properties regarding the ring. The second page contains the ring's specific properties.The ring is drawn in a counter-clockwise direction relative to the radial vector. To reverse this, simply place 180 in the Radius field.Notes: 1. Rings can only be placed on run points.2. Certain elements of this wizard will create new segments in the model. Close Ring, Create new segment and a tee Branch Type will create new segments each.

Answer: Better explaind with and example:
With a segmen going in the +Dy axis (vertical up) direction. Pleace a ring on top using the following entries:
As a result the following rings is created,
Perform the same procedure above, but index the Ring Orientation by 45 deg (i.e. 0, 45, 90, 135, 180). Notice how the ring is rotated about the vertical axis (Offset axis direction) with a counter clockwise rotation.
Perform the same procedure above, but change the Offset = Dx = 5, Dy = 0 feet, Dz = 0 feet and index the Ring Orientation by 45 deg (i.e. 0, 45, 90, 135, 180). Again notice how tthese changes affect the ring creation:
Hint: Imagine your eyeball is looking directly back along the axis created by the Offset direction values. Typically the Ring Orientation will start at 12:00 o'clock, rotating CCW per the value entered (i.e 90 deg = 9:00 - 3:00, 135 deg = 7:30 - 1:30)
