Name Type Cardinality Description
Cone3D ocx:Cone3D_T [1, ∞] Definition of the Cone surface defined by origin, radius and position of the cone tip.
Cylinder3D ocx:Cylinder3D_T [1, ∞] Definition of the cylindrical surface defined by root point, axis direction, radius and height.
ExtrudedSurface ocx:ExtrudedSurface_T [1, ∞]

either a sweep direction and length or a sweep curve. |

NURBSSurface ocx:NURBSSurface_T [1, ∞] Non-uniform rational basis surface definition defined by a net (grid) of polynomial basis functions in U and V direction.
Plane3D ocx:Plane3D_T [1, ∞] Definition of a Planar surface defined by Root Point and Normal.
Sphere3D ocx:Sphere3D_T [1, ∞] Definition of a Spherical surface defined by origin and radius.
SurfaceCollection ocx:SurfaceCollection_T [1, ∞] A collection of any number of surfaces. The surfaces have to be connected (no dis-joint surfaces). Most typically the SurfaceCollection will include the outer shell geometry definition of the vessel.
