ALS005 Alignment shape representation - v3
001 | @implementer-agreement 002 | @ALS 003 | @version3 004 | Feature: ALS005 - Alignment shape representation 005 | The rule verifies that each IfcAlignment uses correct representation. 006 | Checks for entity types are based upon the supported shape representations of IfcAlignment listed in 5.4.3.1. 007 | 008 | Background: 009 | Given A model with Schema 'IFC4.3' 010 | Given An .IfcAlignment. 011 | Given Its attribute .Representation. 012 | Given Its attribute .Representations. 013 | 014 | 015 | Scenario: Agreement on each IfcAlignment using correct representation - Value 016 | 017 | Then .RepresentationIdentifier. ^is^ 'FootPrint' or 'Axis' 018 | 019 | 020 | Scenario: Agreement on each IfcAlignment using correct representation - horizontal only 021 | 022 | Given .RepresentationIdentifier. ^is^ 'Axis' 023 | Given .RepresentationType. ^is^ 'Curve2D' 024 | Given Its attribute .Items. 025 | Then [Its entity type] ^is^ 'IfcCompositeCurve' or 'IfcIndexedPolycurve' or 'IfcPolyline' or 'IfcOffsetCurveByDistances' 026 | 027 | 028 | Scenario: Agreement on each IfcAlignment using correct representation - vertical or cant 029 | 030 | Given .RepresentationIdentifier. ^is^ 'Axis' 031 | Given .RepresentationType. ^is^ 'Curve3D' 032 | Given Its attribute .Items. 033 | Then [Its entity type] ^is^ 'IfcGradientCurve' or 'IfcSegmentedReferenceCurve' or 'IfcIndexedPolycurve' or 'IfcPolyline' or 'IfcOffsetCurveByDistances' 034 | 035 | 036 | Scenario: Agreement on each IfcAlignment using correct representation - identifier = 'FootPrint' 037 | 038 | Given .RepresentationIdentifier. ^is^ 'FootPrint' 039 | Then .RepresentationType. ^is^ 'Curve2D' 040 | 041 | 042 | Scenario: Agreement on each IfcAlignment using correct representation items - Type 043 | 044 | Given Its attribute .Items. 045 | Then [Its entity type] ^is^ 'IfcGradientCurve' or 'IfcSegmentedReferenceCurve' or 'IfcCompositeCurve' or 'IfcIndexedPolycurve' or 'IfcPolyline' or 'IfcOffsetCurveByDistances'
