8.7.3.6 IfcConnectionGeometry

8.7.3.6.1 Semantic definition

IfcConnectionGeometry is used to describe the geometric and topological constraints that facilitate the physical connection of two objects. It is envisioned as a control that applies to the element connection relationships.

The IfcConnectionGeometry allows for the provision of connection constraints between geometric and topological elements, the following connection geometry/topology types are in scope:

• point | vertex point,
• curve | edge curve,
• surface | face surface,
