| Sweep | ocx:Sweep_T | [1, 1] | Definition of the sweep extent by a direction and sweep length. |
| SweepCurve | ocx:CompositeCurve3D_T | [1, 1] | The sweep direction and extent is defined by a general 3D sweep curve. |
| FaceBoundaryCurve | FaceBoundaryCurve | [0, ∞] | A collection of 3D curves making up a closed boundary. |
| PointOnSurface | ocx:Point3D_T | [1, 1] | For multiple surface solutions, a point on the target surface must be provided. |
| Normal | ocx:Vector3D_T | [1, 1] | A unit normal vector to a surface. |
| Description | xs:string | [0, 1] | Contains a description of the component its parent represents. The description is stored as a string. You can use this element for whatever purposes you require. This element can be used inside many OCX XML elements but is optional. |
