4.2.214 Feature_definition

A Feature_definition is a set of parameters and type information representing a feature that is either defined as a component of an item (Included_feature) or independently in its own coordinate space for multiple use (Placed_feature).

Each Feature_definition is a Process_feature_in_solid, a Process_feature_in_panel, or a Replicate_feature.

The data associated with a Feature_definition are the following:

4.2.214.1 is_defined_in

The is_defined_in specifies the Cartesian_coordinate_space_3d in which the feature is defined.

In the case where the Feature_definition is used for defining an Included_feature this Cartesian_coordinate_space_3d shall be the coordinate space in which the Included_feature is defined. In the case where the Feature_definition is used for defining a Placed_feature this Cartesian_coordinate_space_3d is the local coordinate space of the feature.

See feature_definition to cartesian_coordinate_space_3d for the application assertion.

4.2.214.2 location_and_orientation

The location_and_orientation specifies the Axis_placement that defines the location and orientation of the feature.

See feature_definition to axis_placement for the application assertion.

The location_and_orientation need not be specified for a particular Feature_definition.
