4.2.1 Accuracy

An Accuracy is the information about the geometrical accuracy of the product data contained in a model.

The data associated with an Accuracy are the following:

4.2.1.1 accuracy_type

The accuracy_type specifies the kind of accuracy that is applied.

Where applicable the following values shall be used:

4.2.1.2 accuracy_value

The accuracy_value specifies a numerical value defining the Accuracy.

4.2.1.3 description

The description specifies additional information about the Accuracy.

See accuracy to multi_language_string for the application assertion.

The description need not be specified for a particular Accuracy.

If present, there shall be exactly one object that defines the description for an Accuracy.

4.2.1.4 is_defined_for

The is_defined_for specifies the geometry to which the Accuracy is assigned.

NOTE Each object included in accuracy_select is related to zero or one Accuracy_object.

See accuracy to external_geometric_model, accuracy to face, accuracy to geometric_model, accuracy to oriented_edge_curve, and accuracy to vertex_point for the application assertions.

There shall be at least one object that the Accuracy is_defined_for.
