The unbounded surface geometry of the parent element. UnboundedGeometry has the following child elements:
| Child | Namespace | Type | Use | Cardinality | Choice | Description |
|---|---|---|---|---|---|---|
| GridRef | ocx | ocx:GridRef_T | req. | [1, ∞] | True | An element that makes a reference to a grid definition. An offset along the grid reference normal vector can be given. |
| Plane3D | ocx | ocx:Plane3D_T | req. | [1, ∞] | True | Planar surface defined by origin and Normal direction. |
| SurfaceRef | ocx | ocx:SurfaceRef_T | req. | [1, 1] | True | The reference to a Surface geometry which is shared between more than one part. |
