Entity definition

An IfcBoundedCurve is a curve of finite length.

NOTE  Definition according to ISO/CD 10303-42:1992
A bounded curve is a curve of finite arc length with identifiable end points.
NOTE  Entity adapted from bounded_curve defined in ISO10303-42.
HISTORY  New entity in IFC1.0

Informal Propositions:

  1. A bounded curve has finite arc length.
  2. A bounded curve has a start point and an end point.

Attribute inheritance
S[0:1]Assignment of the representation item to a single or multiple layer(s). The LayerAssignments can override a LayerAssignments of the IfcRepresentation it is used within the list of Items.
IFC2x3 CHANGE  The inverse attribute LayerAssignments has been added.
IFC4 CHANGE  The inverse attribute LayerAssignment has been restricted to max 1. Upward compatibility for file based exchange is guaranteed.
S[0:1]Reference to the IfcStyledItem that provides presentation information to the representation, e.g. a curve style, including colour and thickness to a geometric curve.
IFC2x3 CHANGE  The inverse attribute StyledByItem has been added.
IfcDimensionCountThe space dimensionality of this abstract class, defined differently for all subtypes, i.e. for IfcLine, IfcConic and IfcBoundedCurve. X
