Behavior and Limitations of Secondary Shapes for Inline Items

The secondary shapes for inline types will show a different behavior to other kinds of secondary shapes:

• It is not possible to delete the DB item by deleting a secondary shape. If you delete the secondary shape for an inline item, only the shape will disappear. This also means that there is no setting for Deleting a primary shape and Deleting a secondary shape for these types in Diagrams Options.

• The setting Creating secondary shapes on Paste is located in the Pipeline options, Instrumentation line options and HVAC line options instead of in each inline element options. This setting affects all inline elements defined under HVAC, Pipeline or Instrument line.

• Settings: Modifying attributes of secondary shape and Creating secondary shapes on Name Change for tubes duct are located under the Pipeline, Instrument and HVAC lines options. Other inline elements, like valves or fittings, have these settings located under their own options.

• If a secondary shape is copied and pasted without its primary structure, the element will not be defined and the user will be notified by a message in the Message Log.

• It is not possible to make any pipe/HVAC connections to a secondary shape. However, it is possible to connect offline instruments or actuators.

• It is not allowed for any operation that might change the database pipeline/HVAC line connection structure (like join, split, reverse branch, insert valve into structure .)

• If refit/resize or propagation of SCLORE will be executed on a secondary shape and the structure is a segment that ends with OPCO, the system will continue propagation only if it finds the primary OPCI.

• The DIAGREF/PAGEREF attribute of segment is not updated when a secondary shape is created.

• When secondary shapes for more than one shape have been created, for example, for a whole branch or part of a branch, then these secondary shapes will subsequently be handled as a group:

  • It will not be possible to disconnect them from each other.

  • It will not be possible to delete just one of them, the whole group has to be deleted.
