Panel

Structural concept of shipbuilding panels. Panels can typically be composed of plates, seams and stiffeners.

Attributes

Name Type Use Description
GUIDRef ocx:guid optional A globally unique ID referring to an entity in the authoring application. The sending application creates and holds the GUID. Used to establish a unique reference to an entity persistent between applications.
functionType ocx:functionType optional The structure function type giving the structure property function. Follows STEP AP218 coding and IACS Rec 82 Glossary. Enumerator of structure functions which shall be assigned to the parent structure concept.
id xs:ID required An identifier for an element unique within the scope of the XML file. Each id must be unique within a document. The attribute uses the standard XML 1.0 ID type as defined in the XML Schema specification. This attribute is required in many OCX XML elements and an application should generate them automatically.
name xs:string optional An optional descriptive or display name.
tightness ocx:tightness optional A tightness attribute which can be assigned to a Panel or Plate.

Children

Name Type Cardinality Description
UnboundedGeometry ocx:UnboundedGeometry_T [1, 1] The unbounded surface geometry of the parent element.
LimitedBy LimitedBy [1, 1] The references to limiting objects forming a closed contour of the parent element. It is not required that the set of objects is ordered in the correct sequence.
ComposedOf ocx:ComposedOf_T [1, 1] Element representing the structural concepts which composes a structure Panel.
MassProperties ocx:MassProperties_T [0, 1] The mass properties of structure objects (weight and centre of gravity). These properties are provided by the exporting application and can be used as a quality measure by the receiving application to ensure correctness of the import. Both moulded and volume properties can be provided. The volume properties represent the physical mass property of the structure part, while the moulded properties are idealised.
OuterContour ocx:Contour3D_T [0, ∞] The geometry of the outer closed contour limiting a surface, represented by a set of trim curves or a closed curve primitive.
PointOnSurface ocx:Point3D_T [0, 1] For multiple surface solutions, a point on the target surface must be provided.
StiffenedBy ocx:StiffenedBy_T [0, 1] Structural concept defining the stiffeners which belongs to a panel.
SplitBy ocx:SplitBy_T [0, 1] Structural concepts defining the subdivision of a panel into plates split by one or more seams.
CutBy ocx:CutBy_T [0, 1] A structural concept defining a cut-out in a surface defined by a parametric hole or a set of generic trim curves.
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.
CustomProperties ocx:CustomProperties_T [0, 1] Container for custom properties.
