IfcConnectionPointGeometry

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

HISTORY New entity in IFC Release 1.5, has been renamed from IfcPointConnectionGeometry in IFC 2x.
ISSUE See issue log for changes made in IFC Release 1.5 and IFC 2x.

Geometry Use Definitions:

The Cartesian Point defines the point, where the basic geometry items of the connected elements connects.

EXPRESS specification:

ENTITY IfcConnectionPointGeometry
SUBTYPE OF ( IfcConnectionGeometry);
PointOnRelatingElement  :  IfcPoint;
PointOnRelatedElement  :  OPTIONAL IfcPoint;
END_ENTITY;

Attribute definitions:

PointOnRelatingElement  :  Point at which the connected object is aligned at the relating element, given in the LCS of the relating element.
PointOnRelatedElement  :  Point at which connected objects are 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.
