Before a branch can be created, the Current Pipeline must be selected. The Current Pipeline can be viewed in the Status bar (please refer to Status Bar in Chapter Working with Diagrams). To change the Current Pipeline, you can either select the pipeline or any item below it in the explorer, or you can select a tube, a duct or an inline fitting in the drawing which belongs to the desired pipeline.
It is possible to move branches between pipelines by using the Cut and
Paste commands in the Schematic Explorer. However, please note that this will not re-apply any default values, like pipe spec etc., from the receiving pipeline to the branch or its members.
