IFC 4.3.0.0 (IFC4X3) final

Annex E Examples - SpatialStructure_3

Example overview

SpatialStructure_3

Intent

This UT establishes a simple spatial structure for a level crossing (road/railway).

It is based on the storyline SLLC-DD.

Prerequisites

This scenario builds upon following other scenarios: - ProjectSetup_1

Content

This scenario covers the following concepts and/or IFC entities: - spatial structure - IfcSite - IfcRailway - IfcRoad - IfcFacilityPart with correct PredefinedType - IfcRelInterferesElements

Situation

Figure 020db9be-7185-419a-98cb-c7ae0b1502cf

Project Breakdown

To represent the project breakdown for this unit test, we envision the following project structure:

* the PredefinedType enumeration is selected through "IfcFacilityPartTypeSelect".

Expected Results

The aim of this Unit Test, as explained above, is to test the implementation of the project breakdown through the spatial structure concepts of IFC 4.3.

As such, the expected results are:

  1. Screen-shot of the spatial structure breakdown as represented in the native application,
  2. The resulting IFC file containing the spatial structure requested.

For example, the application should be able to display something like what is shown in the picture below:

Figure 75aceb0f-17aa-4586-9773-13e47b94dedc
