Due to the high demand in architecture, engineering and construction industry for standardization in infrastructure projects, the IFC-Bridge, -Road, -Rail projects were launched. This thesis presents the implementation of the entity IfcSectionedSolidHorizontal, introduced with the IFC 4x1 (IFC-Bridge) version of the Industry Foundation Classes standards. This entity is implemented in the IFC 4x3 RC1 format to support the IFC-Road project in the workflow of the open source BIM visualization software being developed at the Technical University of Munich (TUM) called OpenInfraPlatform (OIP). As such, the geometry converter of the OIP was expanded to interpret the IfcSectionedSolidHorizontal. This entity is defined by the sweeping operation of multiple CrossSections(profiles) along the IfcAlignmentCurve which is very useful for supporting bridge and roadway geometry. The visualization of the example files demostrated that the implementation works for the line segment of the alignment curve when the CrossSections all have the same number of points. Despite this, the algorithm should still be further improved to work correctly for CrossSections that have a variable number of profile points and also for the transitions between the curve segments and the line segments.     «
