Building Equipment

When the Integrator builds equipment in the 3D model, the following actions are carried out.

• The names of an appropriate SITE and ZONE are determined from the rules. The SITE and ZONE are created if they do not already exist. If there is no rule to define the SITE or ZONE, Integrator uses the current element, its owner, or the first SITE and ZONE after the current element.c

• EQUIpment is created in the appropriate ZONE and named in accordance with the rules. The name in the 3D model can be a duplicate of the name on the diagram. Alternatively, a rule can be used to construct a name from attributes such as DISTAG (display tag).

• SUBEquipments are created for each schematic subequipment.

• NOZZles are created for each schematic nozzle and ELCONNs for each schematic electrical connection (see below how Integrator deals with nozzles and electrical connections already defined in an equipment template).

• If a specification reference has been set on the schematic equipment it will be copied to the EQUIpment and the equipment template will be instantiated so that it has a population of primitives. The equipment specification can be modified later in the build process.

• If the schematic equipment does not have a specification reference but it does have a description, Integrator collects all the SPCOms and TABITEms from the equipment specifications and selection tables, and looks for a match against the descriptions of their owners. If there is a single match this is set as the specification reference on the 3D equipment.

• If a catalogue reference has been set on a schematic nozzle or electrical connection it is copied to the NOZZle or ELCONN. The specification can be modified later in the build process.

• Nozzle and electrical connection references are set in accordance with the schematic connectivity if the connecting elements exist in the 3D model.

• If a position has been set on the schematic equipment it is copied to the EQUIpment. The equipment position can be modified later in the build process.

• Attribute values can be set on the EQUIpment, based on attribute values on the schematic equipment, in accordance with the rules.

• The schematic and 3D elements are linked.

• Although Integrator always creates nozzles and electrical connections to link to their schematic equivalents, there may already be appropriate nozzles or electrical connections defined in an equipment template. Integrator will check in a template for NOZZles with matching BOREs and for ELCONNs with matching CATREFs. If a match is found, the schematic nozzle or electrical connection are linked to the matched object within the template, and the auto-built NOZZle or ELCONN deleted. Any attribute data, including the name, that were set on the auto-built object in accordance with the rules, will be copied over to the selected 3D connection in the template.

• Connection details can be modified, including changing or swapping the links between 3D and schematic connections. If a link is moved from an auto-built NOZZle or ELCONN in the same session that it was built, the auto-built object is deleted. The specification of the NOZZles and ELCONNs can be modified.

  Note:
  If equipment is built which has no specification set, and then an equipment specification is selected, the auto matching of nozzles and electrical connections will not take place, since Integrator has already finished its build function.

  Note:
  If equipment is built which has a specification set, then the specification is modified, the links and any attribute data copied to the earlier template nozzles and electrical connections are deleted.

Some changes to schematic equipment can be propagated to the 3D model from the Integrator Report, refer to Compare for further information.
