This clause specifies the information requirements for the
Assembly module with cable component 3D
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_3d_arm
schema and identifies the necessary external references.

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.
A Routed_cable_component_3d_shape_model is a type of
Assembly_component_3d_shape_model.
A Routed_cable_component_3d_shape_model is the three-dimensional shape of a
Cable_component.
Sub_model_placement_3d
shall only place connectors that are in the Cable_usage_view
referenced by the shape_characterized_component definition.
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_3d
which provides both location and direction information as the items related by the junction_placement attribute.

Attribute definitions:
cable_path_shape:
specifies the role of the
Curve_swept_solid
for the Routed_cable_component_3d_shape_model.
There shall be one or more
Curve_swept_solid
for the Routed_cable_component_3d_shape_model.
connector_placement:
specifies the role of the
Sub_model_placement_3d
for the Routed_cable_component_3d_shape_model.
There shall be one or more
Sub_model_placement_3d
for the Routed_cable_component_3d_shape_model.
junction_placement:
specifies the role of the
Geometric_model_element_relationship
for the Routed_cable_component_3d_shape_model.
The junction_placement specifies the set of relationships between
Axis_placement_3d
in the usage view shape and a corresponding
Axis_placement_3d
in the Routed_cable_component_3d_shape_model.
These relationships establish the relationships between end points of segments of the 3d solid that represents the cable.
These relationships establish the relationships between end point directions of segments of the 3d solid that represents
the cable.
In particular, when a
Curve_swept_solid
is used, each of the
Axis_placement_3d
forms a directrix for a start point of the solid segment. There may be more than one
Geometric_model_element_relationship
for the Routed_cable_component_3d_shape_model. The items related by
Detailed_geometric_model_element_relationship
referenced by junction_placement shall only be
Axis_placement_3d.
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_3d,
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_3d_shape_model. There shall be exactly one
Cable_component
for the Routed_cable_component_3d_shape_model.
Formal propositions:
WR1:
The
description
shall not be populated.
A Sub_model_placement_3d 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
or
Routed_cable_component_3d_shape_model.
The dimensionality of the Sub_model_placement_3d 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_3d;

Attribute definitions:
placement:
specifies the role of the
Axis_placement_3d
for the Sub_model_placement_3d.
sub_model:
specifies the role of the
Component_3d_location
for the Sub_model_placement_3d.
The sub_model is in the context of the usage view.
