IFC4.3AbRV_E2a_SB01	(RFI) Track sub-structure for single track	E2a (TRAS)	SB01	Evandro Alfieri	RFI	1.0	DD.MM.YYYY

Summary (Intent)

This test case addresses the export of the required IFC entities for the exchange of track sub-structure information.

This test case focuses only on track sub-structure (red in picture below). For the track super-structure part (green in picture below), refer to test case IFC4.3AbRV_E2a_SP01, of which SB01 is a pre-condition.

Snippet:

• Refer to Test Case Imports to know the prerequisites for the present test.

• The Expected Results section lists the material that will be used to assess the fulfilment of capabilities.

• This is a test-driven process: refer to the Validation Criteria to understand what is required by the test

Itemised Roots

under construction, check CT for product shape

The Test instruction addresses the import and export of the following IFC Entities & Concept Templates:

IFC Entities

These entities represent a test-specific subset of the wider AbRV_E2a exchange and the overall AbRV MVD. The scope of the test shall not be used as a definitive scope of the exchange, or of the MVD

• Products:
  1. IfcCourse / IfcCourseType
  2. IfcEarthworksFill

Concept Templates

These concept templates represent a test-specific subset of the wider AbRV_Ex exchange and the overall AbRV MVD, that must be correctly exported to meet the validation criteria. The scope of the test shall not be used as a definitive scope of the exchange, or of the MVD

• Object Attributes
  • Object Predefined Type
• Object definition
  • Object Typing
• Product Shape
  • Product Geometric Representation
  • Body SectionedSolidHorizontal
• Object Connectivity
  • Spatial Containment
• Product Placement
  • Product Local Placement
  • Product Linear Placement

Model Dataset

This test case utilises the dataset collected in the Dataset folder and summarised in the table below. For more details on each item see Dataset description.

TrackCrossSection	drawing (png)	Track cross section to be used as example

Test Case Imports

All validation criteria (and usages) of predecessors' tests shall be verified for this test too (regression test principle). Prerequisites for the present test case are listed below.

TI Code	Test Instruction Title	Comments
IFC4x3_AbRV-E1-AL22	(RFI) Two alignments without cant	For the test to be passed, the track sub-structure shall be modelled ONLY for the Primary Route (i.e., Alignment 1_Primary route)

Expected Results

For certification of capabilities the only source will be:

• n. 1 IFC file containing the information as requested. The file shall be named using the following syntax: MVDCodeExchangeCodeTestCode_SoftwareVendor.ifc (Example: IFC4.3AbRV_E2a_SB01_AmazingSoft.ifc)

Validation criteria

For this test case to be considered passed all capabilities listed in this section, and the ones of pre-required tests shall be verified, with no exception.
