ISO 10303-214:2010(E)
A Feature_occurrence is the identification of a feature that is applied on an Item_shape.
NOTE 1 It is therefore an aspect of this shape.
If a Feature_occurrence is related to shape information by a Shape_description_association, the representing model shall refer to the same Cartesian_coordinate_space as any representation of the Item_shape in which the feature occurs.NOTE 2 For the description of the rationale behind the application of a feature (e.g., the feature function, the inherited 'description' attribute may be used.
A Feature_occurrence is a type of Shape_element.
Each Feature_occurrence is an Included_feature or a Placed_feature.
The data associated with a Feature_occurrence are the following:
maximum_feature_limit
The maximum_feature_limit specifies the Plane beyond which a machining tool has cleared the feature.
See feature_occurrence to plane for the application assertion.
