Part and Equipment Definition
This section explains what a part is and what an item of equipment is.
A part is a 3D entity obtained by combining different features. It can be inserted on trays. Examples include tees, elbows, gaskets and flanges.
An item of equipment is also a 3D entity and can be connected to trays. Examples include pumps, actuators and tanks.
Parts placed in the design are generally considered as standard parts. If the same part is placed in two different locations in the design, then these two parts have the same part number, however their instance ID, instance attributes, and instance positions are different.
A part can have multiple representations. Each representation is used to meet specific design criteria. For example, an envelope representation may be used for interference verification while a simple line representation may be used when generating congested plan drawings.
