CIM Issues #5296
5295:5297:5296 - WG14 Part 4 WireAssemblyInfo and related cleanup for ACLineSegment physical modeling
61968-11, 61968-4
Description
This issue describes the 61968 Part 4 changes which are the only subset of the 61968 changes related to CIM Issue #5295 (Joint issue on ACLineSegment physical modeling clarification).
Files
Proposed Solution
At a high level the following are proposed:
WireSpacingInfo - Repurpose class for use only in describing collections of wires carrying a single phase. Rename class to IntrphaseSpacing, remove .isCable and .usage attributes, create new associations to ACLineSegmentPhase and WirePosition to allow it to be used in the 3 templating approaches. Also remove no-longer-needed WireUsageKind class.
WirePhaseInfo - Remove class and its 3 associations. Relocate its only attribute (.phaseInfo) to the WirePosition class.
WireAssemblyInfo - Rename class and add 3 associations to allow it to serve as the only class supporting the description of collections of wires carrying multiple phases.
Decision
Part 4 has been updated according to the proposed solution.
Release Notes
61968 changes
Change class name WireAssemblyInfo to WireAssembly
Change association role name PerLengthLineParameter.WireAssemblyInfo to PerLengthLineParameter.WireAssembly, ensuring that association has PerLengthLineParameter as source and WireAssembly as target
Add association ACLineSegment.WireAssembly, ensuring that association has ACLineSegment as source and WireAssembly as target
Add association WirePosition.WireAssembly, ensuring that association has WirePosition as source and WireAssembly as target
Change inheritance WireAssembly to inherit from IdentifiedObject instead of AssetInfo and move WireAssembly to the 61970 package
Move WirePosition to the 61970 package
Add association WirePosition.WireInfo ensuring that association has WireInfo as source and WirePosition as target as it crosses the 61968/61970 boundary
Add attribute WirePosition.phase
Delete class WirePhaseInfo
Delete association WirePhaseInfo.WireAssemblyInfo
Delete association WirePhaseInfo.WirePosition
Delete association WirePhaseInfo.WireInfo
Delete attribute WireSpacingInfo.isCable
Delete attribute WireSpacingInfo.usage
Delete class WireUsageKind
Change class name WireSpacingInfo to IntraphaseSpacing
Change attribute name WireSpacingInfo.phaseWireSpacing to IntraphaseSpacing.wireSpacing
Change attribute name WireSpacingInfo.phaseWireCount to IntraphaseSpacing.wireCount
Delete association ACLineSegment.WireSpacingInfo
Change association role name WirePositions.WireSpacingInfo to WirePosition.IntraphaseSpacing, ensuring that association has WirePosition as source and IntraphaseSpacing as target
Add association IntraphaseSpacing.ACLineSegmentPhase ensuring that association has ACLineSegment as source and IntraphaseSpacing as target
Change inheritance IntraphaseSpacing to inherit from IdentifiedObject instead of AssetInfo and move IntraphaseSpacing class to 61970 package
