Selecting End Components
When merging pipelines, Spec-Driven Piping selects the end components based on the following:
If you do not specify end components when merging pipelines, all the components located in the downstream direction of the specified start pipe segment or fitting are associated with the selected To Pipeline during the merge operation.
The start and the first end piping components that you specify are used to check the validity of the subsequent end components.
Though you can select a break fitting as a bound when merging pipelines, the merge operation starts from the adjacent fitting or pipe segment within the selected boundary. Therefore, the From Pipeline retains the break fitting in this case.
Spec-Driven Piping highlights the connected portion of the pipeline with a larger point size. This point size is displayed until the pipeline is merged, or until you select a new start segment or a fitting, or until you end the session.
