| [[.:compositecurve3d|CompositeCurve3D]] | ocx:CompositeCurve3D_T | [1, 1] | The concept of a composite curve composed of a collection of Line3D, CircumArc3D and/or NURBS segments. Curves are sorted end to end and have C0 continuity across each segment in the CompositeCurve3D definition. |
| [[.:edgecurveref|EdgeCurveRef]] | EdgeCurveRef | [0, 1] | A reference to a Panel, Plate or bracket boundary curve. Used as landing curve for a faceplate or edge reinforcement stiffener. |
| [[.:edgereinforcementref|EdgeReinforcementRef]] | ocx:EdgeReinforcementRef_T | [0, 1] | A reference to a structure EdgeReinforecement instance. |
| [[.:gridref|GridRef]] | GridRef | [0, 1] | An element that makes a reference to a grid definition. An offset along the grid reference normal vector can be given. |
| [[.:panelref|PanelRef]] | PanelRef | [0, 1] | The reference to a connected Plate. |
| [[.:seamref|SeamRef]] | SeamRef | [0, 1] | The reference to a connected Plate. |
| [[.:stiffenerref|StiffenerRef]] | StiffenerRef | [0, 1] | A  reference to a Stiffener. |
| [[.:surfaceref|SurfaceRef]] | SurfaceRef | [0, 1] | The reference to a Surface geometry which is shared between more than one part. |
