IfcConnectionSurfaceGeometry

Definition from IAI: The IfcConnectionSurfaceGeometry is used to describe the geometrical constraints that facilitate the physical connection of two objects at a surface (IfcSurface). It is envisioned as a control that applies to the element connection relationships.

HISTORY New entity in IFC Release 2x.
ISSUE No issues raised so far.

Geometry Use Definitions:

The surface defines the segments, where the basic geometry items of the connected elements connects.

EXPRESS specification:

ENTITY IfcConnectionSurfaceGeometry
SUBTYPE OF ( IfcConnectionGeometry);
SurfaceOnRelatingElement  :  IfcSurface;
SurfaceOnRelatedElement  :  OPTIONAL IfcSurface;
END_ENTITY;

Attribute definitions:

SurfaceOnRelatingElement  :  Surface at which related object is aligned at the relating element, given in the LCS of the relating element.
SurfaceOnRelatedElement  :  Surface at which the relating element is aligned at the related element, given in the LCS of the related element. If the information is omitted, than the origin of the related element is used.
