To Create the Pipeline Model for a Pipeline with Loop Series
1. Create three pipe segments from the coordinate system ACSO in the directions, Positive Z, Positive Y, and Negative X. The default flow direction for the series is determined by Flow Direction Rule 1.
2. Create a branch segment in the Negative Z direction from point APNT1. This segment ends within point APNT2 along the Negative Z direction. The default flow direction for the downstream series created during branching at point APNT1 is determined by Flow Direction Rule 2.
3. Create a pipe segment from point APNT2 in the Positive Y direction.
4. Connect the segments created in steps 2 and 3 as shown in the example. The default flow direction for the branch series is determined by Flow Direction Rule 3.
