4 Information requirements

This clause specifies the information requirements for the Assembly module with cable component 2D application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.

NOTE 1  A graphical representation of the information requirements is given in Annex C.

NOTE 2  The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.

The following EXPRESS specification begins the Assembly_module_with_cable_component_2d_arm schema and identifies the necessary external references.

EXPRESS specification:

4.1 Required AM ARMs

The following EXPRESS interface statements specify the elements imported from the ARMs of other application modules.

4.2 ARM entity definitions

This subclause specifies the ARM entities for this module. Each ARM application entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entities and definitions are specified below.

4.2.1 Routed_cable_component_2d_shape_model   EXPRESS-GMapping table

A Routed_cable_component_2d_shape_model is a type of Assembly_component_2d_shape_model. A Routed_cable_component_2d_shape_model is the two-dimensional shape of a Cable_component. The shape of the cable in the assembly may only differ from the shape of the cable in the usage view in the details of the curve set geometry. The overall path length of any curve or segment shall not be different, and the direction of the curve or segment as it relates to the connector end of the curve or segment that it is geometrically related to shall not change. These constraints are supported by using Axis_placement_2d which provides both location and direction information as the items related by the junction_placement attribute.

EXPRESS specification:

ENTITY Routed_cable_component_2d_shape_model
  SUBTYPE OF (Assembly_component_2d_shape_model);
  cable_path_shape : SET[1:?] OF Curve;
  connector_placement : SET[1:?] OF Sub_model_placement_2d;
  junction_placement : OPTIONAL SET[1:?] OF Geometric_model_element_relationship;
  SELF\Assembly_component_2d_shape_model.shape_characterized_component : SET[1:1] OF Cable_component;
WHERE
  WR1: NOT EXISTS(SELF\Representation.description);
END_ENTITY;
(*

Attribute definitions:

cable_path_shape: specifies the role of the Curve for the Routed_cable_component_2d_shape_model. There shall be one or more Curves for the Routed_cable_component_2d_shape_model.

connector_placement: specifies the role of the Sub_model_placement_2d for the Routed_cable_component_2d_shape_model. There shall be one or more Sub_model_placement_2d for the Routed_cable_component_2d_shape_model.

junction_placement: specifies the role of the Geometric_model_element_relationship for the Routed_cable_component_2d_shape_model. There may be more than one Geometric_model_element_relationship for the Routed_cable_component_2d_shape_model. The junction_placement specifies the set of relationships between Axis_placement_2d in the usage view shape and a corresponding Axis_placement_2d in the Routed_cable_component_2d_shape_model. These relationships establish the relationships between end points of segments of the curve set that represents the cable. These relationships establish the relationships between end point directions of segments of the curve set that represents the cable. The items related by Detailed_geometric_model_element_relationship referenced by junction_placement shall only be Axis_placement_2d. A junction_placement must be provided for each end point of each segment in the usage view that is desired to be related to a segment end point in the design view. The value of this attribute need not be specified.

NOTE    Since the items related are Axis_placement_2d, there is no need for transformation matrix to transform from the source context into the target context.

shape_characterized_component: specifies the role of the Cable_component for the Routed_cable_component_2d_shape_model. There shall be exactly one Cable_component for the Routed_cable_component_2d_shape_model.

Formal propositions:

WR1: The description shall not be populated.

4.2.2 Sub_model_placement_2d   EXPRESS-GMapping table

A Sub_model_placement_2d is the placement of the shape of a Packaged_connector from a cable shape sub model in a usage view into the current design view as referenced by an instance of Routed_cable_component_2d_shape_model. The dimensionality of the Sub_model_placement_2d shall be the dimensionality of the current geometric context into which the shape is being placed. The dimensionality of the sub_model shall be the same as the dimensionality of the placement. The placement shall be in the geometric context of the design view.

EXPRESS specification:

*)
ENTITY Sub_model_placement_2d;
  placement : Axis_placement_2d;
  sub_model : Component_2d_location;
END_ENTITY;
(*

Attribute definitions:

placement: specifies the role of the Axis_placement_2d for the Sub_model_placement_2d.

sub_model: specifies a role of the Component_2d_location for the Sub_model_placement_2d. The sub_model is in the context of the usage view.
