In complex piping projects that involve multiple design changes and revisions, large piping systems are initially modeled as a single pipeline without considering the various connected pipelines. At a later stage in the design process, you can split the components of the large pipeline progressively into individual pipelines. This method of pipeline design provides flexibility and improves productivity.

You can also separate different portions of a single pipeline into multiple pipelines. This is possible when you create the required pipelines using the Create Pipeline dialog box. You can then use the merge tool to select and merge the required connected portion of the pipeline to the respective pipeline.
