IfcRoundedRectangleProfileDef

IfcRoundedRectangleProfileDef

Definition from IAI: The IfcRoundedRectangleProfileDef defines a rectangle with equally rounded corners as the profile definition used used by the swept surface geometry or the swept area solid. It is given by the X extent, the Y extent, and the radius for the rounded corners, and placed within the 2D position coordinate system, established by the Position attribute. It is placed centric within the position coordinate system.

HISTORY: New class in IFC Release 2x
ISSUE: See issue and change log for changes made in IFC Release 2x.

ILLUSTRATION

Position
The Position attribute defines the 2D position coordinate system of the rounded rectangle.

Parameter
The IfcRoundedRectangleProfileDef is defined within the position coordinate system, where the XDim defines the measure for the lenght of the rectangle (half along the positive x-axis), the YDim defines the length measure for the width of the rectangle (half along the positive y-axis) and the RoundingRadius defines the radius of the fillet which is equally applied to all edges of the rectangle.

Attribute definitions:

Position	:	Position coordinate system of the rounded rectangle profile definition.
XDim	:	The extend on the implicit x-axis of the underlying rectangle.
