ISO 10303-214:2010(E)
A General_shape_dependent_property is a user-defined characteristic of an object. The 'property_value' specified by a General_shape_dependent_property is derived from geometry.
NOTE The General_shape_dependent_property may be used for the purpose of validation of geometric models.
EXAMPLE If a geometry model is exchanged between two partners, the calculation of various properties of the bodies, such as centre of mass, overall surface, or overall volume, is performed by originator and recipient. When comparing these set of values, the existence of deficiencies in the received model can be easily detected.
A General_shape_dependent_property is a type of Shape_dependent_property.
The data associated with a General_shape_dependent_property are the following:
The property_type defines the type of characteristic that is specified for an object.
The following values shall be used:
EXAMPLE An example, where the use of this General_shape_dependent_property with property_type 'centroid' is used instead of the object Centre_of_mass, is the following: sometimes the General_shape_dependent_property is calculated by some system at some point of time. But there are cases where the information, e.g., the General_shape_dependent_property of a die, is transferred into a following stage, e.g., in order to perform a feasibility check, where there is only a simplified shape representation that does not allow to calculate the exact General_shape_dependent_property. Yet, in this stage the information about the General_shape_dependent_property is needed in order to check whether the transport of a die with a crane is feasible.
The property_value specifies the value that is given for a particular characteristic.
The unit_component specifies the unit in which the General_shape_dependent_property is expressed.
The unit_component need not be specified for a particular General_shape_dependent_property.
