4.2.466 Shape_dependent_property

A Shape_dependent_property is a characteristic of the shape, or of a portion of the shape of an object. This object is either an item, an occurrence of an item in the product structure or the physical realization of an item.

NOTE A Shape_dependent_property is independent of the representations of the shape.

Each Shape_dependent_property is a Centre_of_mass, a Moments_of_inertia, or a General_shape_dependent_property.

The data associated with a Shape_dependent_property are the following:

4.2.466.1 described_element

The described_element specifies the object that the Shape_dependent_property is associated to.

See shape_dependent_property to item_shape and shape_dependent_property to shape_element for the application assertions.

There shall be exactly one object that defines the described_element for a Shape_dependent_property.

4.2.466.2 description

The description specifies additional information about the Shape_dependent_property.

See shape_dependent_property to multi_language_string for the application assertion.

The description need not be specified for a particular Shape_dependent_property.

If present, there shall be exactly one object that defines the description for a Shape_dependent_property.

4.2.466.3 is_defined_in

The is_defined_in specifies the Cartesian_coordinate_space in which the property is applicable.

NOTE The values of geometry related properties are specified relative to a Cartesian_coordinate_space.

EXAMPLE A Centre_of_mass may be specified in different coordinate spaces for different dimensioning applications.

See shape_dependent_property to cartesian_coordinate_space for the application assertion.

The is_defined_in need not be specified for a particular Shape_dependent_property.

4.2.466.4 value_determination

The value_determination specifies information on how the Shape_dependent_property shall be interpreted.

Where applicable the following values shall be used:

NOTE A Shape_dependent_property may be specified in the design stage of a product but it may also be documented as measured on a manufactured part.

The value_determination need not be specified for a particular Shape_dependent_property.
