ISO 10303-214:2010(E)
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:
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.
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.
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.
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.
