IfcParameterizedProfileDef
Definition from IAI: The parameterized
profile definition
defines a 2D position coordinate system to which the parameters of the
different profiles relate to. All profiles are defined centric to the
origin of the position coordinate system, or more specific, the origin
[0.,0.] shall be in the center of the bounding box gravity
of the profile.
The Position attribute of the IfcParameterizedProfileDef
is used to position the profile within the XY plane of the underlying
coordinate system of the swept surface geometry, the swept area
solid or the sectioned spine. It can be used to position the profile at
any cardinal point that becomes the origin [0.,0.,0.] of the extruded
or rotated surface or solid.
HISTORY
New entity in
Release IFC2x Edition 2.
IFC2x
Platform CHANGE The IfcParameterizedProfileDef
is introduced as an intermediate new abstract entity that unifies the
definition and usage of the position coordinate system for all
parameterized profiles. The Position attribute has been removed at all
subtypes (like IfcRectangleProfileDef, IfcCircleProfileDef,
etc.).
IFC2x Edition 3 CHANGE All profile
origins are now in the center of the bounding box.
