The references to limiting objects forming a closed contour of the parent element. It is not requiredthat the set of objects is ordered in the correct sequence. LimitedBy has the following child elements:
| Child | Namespace | Type | Use | Cardinality | Choice | Description |
|---|---|---|---|---|---|---|
| FreeEdgeCurve3D | ocx | ocx:FreeEdgeCurve3D_T | req. | [1, ∞] | True | Collection of non-closed Curve3D types. Used to represent a free edge to form a closed contour together with the limiting objects. |
| 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. |
| OcxItemPtr | ocx | ocx:OcxItemPtr_T | req. | [1, ∞] | True | A generic element used to reference an instantiated OCX object by a GUID (the pointer). |
