Error T1: There is no template_proxy in the capability assigning_product_properties for the template product_property_geometric

This section specifies the template product_property_geometric.

NOTE The template has been defined in the context of the capability assigning_product_properties which provides an overall description of the relevant parts of the ISO 10303-239 information model and a description of related templates.

NOTE An explanation of a template and the associated instantiation path is provided in the Template overview section.

Description

This template describes the representation of a property that is geometric.

Model diagrams

The EXPRESS-G diagram in Figure 1 shows the templates and EXPRESS entities that are required to represent the template "product_property_geometric". The text highlighted in blue shows the template parameters.

The graphic for the template to be used in other EXPRESS-G diagrams is shown in Figure 2 below.

Input parameters

The following input parameters are defined for this template:

rep (Type= 'ENTITY (Geometric_model)' )

The geometric model that supplies the property representation.

property (Type= 'ENTITY (Assigned_property)' )

The assigned property that has a geometric representation.

Reference parameters

The following reference parameters are defined for this template:

prop_ref(Type='ENTITY (Property_representation)')

Allow the Property_representation entity instantiated in this path to be referenced when this template is used.

Note: The Property_representation entity can be referenced in a template path by:

%^target = $product_property_geometric.prop_ref%

where target is the parameter to which the Property_representation is bound.

Instantiation path

The instantiation path shown below specifies the entities that are to be instantiated by the template.

A description of templates and the syntax for the instantiation path is provided in the Templates Help/Information section.

-- Instantiate Property_representation entity
Property_representation

-- Set the unused Property_representation attributes to be ignored
Property_representation.description = '/IGNORE'
Property_representation.role = '/IGNORE'

-- Bind the Property_representation to the parameter ^prop_rep
%^prop_rep = Property_representation%

-- Set the used Property_representation attributes to the corresponding input parameters
Property_representation.rep -> @rep
Property_representation.property -> @property

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
Property_representation.description	'/IGNORE'	—
Property_representation.role	'/IGNORE'	—

Instance diagrams

The instance diagram in Figure 3 shows an example of the EXPRESS entities and templates that are instantiated by the template:

/product_property_geometric(rep='@8', property='@property')/

(an illustration of the consolidated product_property_geometric template is shown in Figure 4 below.)

Figure 3 — Entities instantiated by product_property_geometric template

The instance diagram in Figure 4 shows the graphic symbol for the template that is to be used in other instance diagrams. The example template is:

/product_property_geometric(rep='@8', property='@property')/

Characterizations

No common characterizations of the template product_property_geometric have been identified. However, the ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.
