Creo TOOLKIT supports Piping. Piping uses specific terminology. This section defines this terminology.

A pipeline is set of interconnecting pipes and fitments. A pipeline consists of an extension which terminates at open ends (that is, ends with no further pipeline items are attached), non-open ends (that is, ends with equipment such as nozzles or other pipelines), or junctions. A pipeline also contains extensions that branch from extensions which branch from it, then others which branch from those, and so on.

A pipeline extension is a non-branching sequence of pipeline items.

A pipeline feature is a feature which names the pipeline to show its grouping. All other features in the pipeline refer to this feature. A pipeline feature does not contain any geometry of its own.

At a branch (or junction), pipes are grouped into extensions such that the extension which continues across the branch has a continuous direction of flow, and, if that criterion leaves a choice, has the smallest change of direction possible for that branch. Other pipes which join that branch then form the end points of other extensions.

A member of an extension is a terminator, a series, or a junction.

A terminator is the open or non-open ends of the pipeline.

A series is a non-branching sequence of pipeline objects.

A junction is an assembly component or a datum point which represents a part which joins three or more pipe segments.

A stubin is a datum point which joints three or more series.

A segment is a section of pipe, either straight or arced. If arced, the segment is manufactured by taking a straight section of tube and bending it.

A fitting is a component that connects two pipe segments, for example, to form a corner where space does not allow a bent pipe segment, or to represent an item such as a valve

A pipeline object is a segment, a fitting, or a stubin.

A pipeline network is a data structure which contains references to pipeline objects. The objects are structured to show their connectivity and sequence in relation to the flow.
