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.
