Definition from IAI: The IfcConnectionCurveGeometry is
used to describe the geometric constraints that facilitate the physical
connection of two objects at a curve (IfcBoundedCurve). It is envisioned
as a control that applies to the element connection relationships.
EXAMPLE: The connection relationship between two walls
has a geometric constraint which describes the end caps (or cut-off of the wall
ends) by a CurveOnRelatingElement for the first wall and a
CurveOnRelatedElement for the second wall. The exact usage of the
IfcConnectionCurveGeometry is later defined at the geometry use
sections of the elements, using it.
The available geometry for the connection constraint may be further
restricted to only allow straight segments by applying IfcPolyline
only.
HISTORY: New entity in IFC Release
1.5, has been renamed from IfcLineConnectionGeometry in IFC 2x.
ISSUE: See
issue log for changes made in IFC Release 1.5 and IFC 2x.
Geometry Use Definitions:
The bounded curve defines the line (and arc) segments where the basic
geometry items of the connected element connects.
