Position | MODIFIED | Instantiation changed to OPTIONAL. |
IfcRoundedRectangleProfileDef defines a rectangle with equally rounded corners as the profile definition 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, that is, in the center of the bounding box.
HISTORY New entity in IFC2x.
IFC2x CHANGE The IfcRoundedRectangleProfileDef is now subtyped from IfcRectangleProfileDef. The XDim and YDim attributes have been removed (now inherited from supertype).
Figure 398 illustrates parameters of the rounded rectangle profile definition.

IfcProfileDef | |||||
1 | ProfileType | IfcProfileTypeEnum | [1:1] | Defines the type of geometry into which this profile definition shall be resolved, either a curve or a surface area. In case of curve the profile should be referenced by a swept surface, in case of area the profile should be referenced by a swept area solid. | X |
2 | ProfileName | IfcLabel | [0:1] | Human-readable name of the profile, for example according to a standard profile table. As noted above, machine-readable standardized profile designations should be provided in IfcExternalReference.ItemReference. | X |
HasExternalReference | IfcExternalReferenceRelationship @RelatedResourceObjects | S[0:?] | Reference to external information, e.g. library, classification, or document information, which is associated with the profile. | X | |
HasProperties | IfcProfileProperties @ProfileDefinition | S[0:?] | Additional properties of the profile, for example mechanical properties. | X | |
