Main Functions : Build a Missing Element

Build a Missing Element

Integrator can create 3D data directly from the schematic data, enabling equipment, pipeline, HVAC and cable elements to be built automatically in 3D model, populated with data from the schematic model. This means for example that an equipment list and line list can be propagated to the 3D model along with all their key process data, tags and inter-connections. Refer to How Integrator Builds 3D Data, Building Equipment, Building Pipework, Building Missing Elements, Building Multiple Pipes for a Single Schematic Pipeline, Building HVAC, Building Cable and Building Offline Instruments for further information.

Thus when schematic data is available, Integrator can provide an initial population of corresponding elements in the 3D model. As updates occur in the schematic data, these can be applied to the 3D data in a controlled process. Each project can control precisely which data is transferred from schematic to 3D, what types of object are created, and which attributes are set, using easily configured rules.

When Integrator builds an object in the 3D model, that object is automatically linked with its corresponding schematic object. Refer to Schematic and 3D Links for further information.

Note:

Integrator can build in the current SITE and ZONE if there is no rule to define the SITE or ZONE. In order to get Integrator to build in the current ZONE, use the Main Table > Build. Click in the Diagram Viewer to use its right click menu, the current element will be changed to the schematic object, and Integrator will no longer be able to build in the intended ZONE.

During the build process, Integrator automatically copies over the value of any attribute that appears on both the schematic and 3D object, for example: Description. The exact set of attributes varies according to type. To suppress this functionality, create an Assign Rule for that type and attribute and setting its Build Action to ignore. Refer to Build and Compare Rules for more detail.

The Build functionality can be accessed from the Command Line, refer to Use Integrator from the Command Line for further information.

In the information panel of the Integrator Report, the missing element is identified at schematic and 3D element pipe, branch and component level.

Use the right click menu to display the available functionality, the Build option is available for selection.

Note:

The Build functionality is only available when the element is not linked or matched.

Select Build to create the missing element.

Updating an Attribute Value from the Integrator Report

When Integrator finds that an attribute value in the 3D model that does not conform to the rules, for example when a specification has been changed on the diagram but not yet updated to the 3D model, a drop-down menu or right click menu is displayed in the Integrator Comments window to correct the inconsistency.

Use the left click to display further information on the inconsistency in the status bar of the Integrator Comments window.

To amend the attribute to match the diagram, from the right click menu, select Copy to 3D.

Alternatively, select the correct attribute from the drop-down menu provided.

Once the update has been completed, the field will turn cyan in colour.

How Integrator Builds 3D Data

When the Integrator builds in 3D it carries out a set of actions under the control of the Configuration Rules. The rules are described in detail in Build and Compare Rules.

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.

Building Pipework

When the Integrator builds pipework 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.

•

A PIPE is created in the appropriate ZONE and named in accordance with the rules. Typically the name is generated from a number of schematic pipeline attribute values and can include a sequential number.

•

BRANches are created equivalent to the schematic branches.

•

Piping elements are created equivalent to schematic piping instruments, valves and fittings. Rules determine the component type. Elements (including valves and instruments) can be named if rules are defined for this.

•

Component specification references are copied from the schematic elements where available.

•

If a specification reference has not been set on the schematic component, Integrator tries to choose the 3D component from a pipe specification using available data. Integrator determines the appropriate specification, generic type and bore(s). Other selectors such as STYPE can be set by the rules. If Integrator has insufficient data to make a single choice, a warning is displayed in the Integrator Comments window, along with a drop down menu populated with specifications available for selection.

•

Connection references are set in accordance with schematic connectivity if the connecting elements exist in the 3D model. This includes branch head and tail references, nozzle connection references, component connection references and connection reference arrays.

•

Attribute values can be set on the 3D pipes and elements, based on attribute values on the schematic pipelines and elements, in accordance with the rules.

•

The schematic and 3D elements are linked.

•

Resolve connections where the schematic connection is directly to schematic equipment. In the 3D model the connection must be to a nozzle or electrical connection. When resolving connections the user can select an existing nozzle or electrical connection or create a new connection.

•

Where a number of interconnected schematic pipelines are to be built in the 3D model, it is recommended to build the main line first, before building offlegs.

Building Missing Elements

Integrator can build missing piping elements from the Integrator Report, refer to Compare for further information.

Building Multiple Pipes for a Single Schematic Pipeline

Currently it is not possible to automatically build part of a schematic pipeline into a pipe, or to automatically build several pipes from a single schematic pipeline. If a schematic pipeline is to be represented in the 3D model as multiple pipes, each pipe must be created using the Pipework application, and then linked to the schematic pipeline. Individual elements could then be built in the 3D model from the Integrator Report, refer to Compare for further information.

Integrator builds HVAC in the 3D model using a process that is equivalent to that for creating pipework, but based on schematic HVAC lines, and with its own family of rules.

Integrator uses a look-up table of information relating to the standard AVEVA HVAC component specification. This data is read from the file HVACStypeTable.xml which is included in the AVEVA E3D™ or marine executables folder. Integrator looks for this file first in the %<proj>dflts%\modelmanagement folder and then in the AVEVA_DESIGN_EXE folder. This file can be modified to suit company or project requirements.

Integrator can build and compare HVAC data provided that the schematic data is consistent with the standard AVEVA HVAC application catalogue. This means that any HVAC fittings defined on a diagram must conform to the equivalent 3D HVAC fittings that can be created from the standard AVEVA 3D HVAC specification.

The information used by Integrator to determine the appropriate component in the 3D model depends on the following attributes of the SCHVFI (schematic HVAC fitting) object:


GTYP	generic type
SCSTYP	specific type
CONARRAY	duct shapes for each connection point
WIDARRAY	duct widths for each connection point
HEIARRAY	duct heights for each connection point

In order for Integrator to be able to build and compare a 3D HVAC component, the combination of this information from the SCHVFI must correspond to a component in the standard catalogue. In particular, if there is a branch connection point, it should be P3, with ARRIVE and LEAVE as P1 and P2 (or P2 and P1) respectively.

An example of a component that would not meet this criteria would be a rectangular, three-way fitting with a different duct height on P3. In the standard catalogue, duct height (the depth of the fitting) is equal across the three connection points.

For each GTYP there are one or more available SCSTYPs. To set an appropriate SCSTYP in AVEVA Diagrams in HVAC mode, navigate to the SCHVFI by selecting it in the diagram or schematic explorer, click on HVAC > Set SCSTYP, select an SCSTYP from the list and click Apply.

Integrator builds user defined HVAC fittings provided that the SPREF is set on the SCHVFI. A configuration rule should be defined in Integrator for SCHVFI elements, to copy the SPREF if it is set on the source element.

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

•

The names of an appropriate SITE and ZONE are determined from the rules.

•

A CABLE is created in the appropriate ZONE and named in accordance with the rules.

•

Start and End references are set in accordance with schematic connectivity if the connecting elements exist in 3D. Connections can be direct to equipment using the ELCXRF attribute or to ELCONNs.

•

Attribute values can be set on CABLES in accordance with the rules.

•

The schematic and 3D elements are linked.

Integrator does not create CORE elements below 3D cables, even if the schematic cable owns schematic cores. If needed, schematic core data can be referenced from the 3D model via the owning cable's SCHLNK attribute.

Integrator builds the individual cables for a Schematic Multi-Cable (SCMCAB). There is no 3D model equivalent of SCMCAB.

Building Offline Instruments

Integrator builds offline instruments in the 3D model as EQUIpment. In this context, offline instruments are instruments remote from the pipework (as opposed to instruments modelled as branch members even if they are located off the centreline of the pipe).
