Equipment and equipment nozzle objects are included within the line list application's design basis for the sole purpose of providing line segment "from" and "to" connectivity information. Only enough information is retrieved for equipment and equipment nozzles as is required to support the from/to connectivity for the connected line segments.
Since equipment and equipment nozzles are part of the design basis, they are not editable and can only be created, deleted, or modified by retrieval from another application.
