ISO 10303-214:2010(E)
A Pocket_feature is the result of the removal of a volume from a shape. The removed volume is defined by a profile that is swept along a path. Additional characteristics regarding the bottom of the pocket or the walls of the pocket may also be specified.
A Pocket_feature is a type of Process_feature_in_solid.
Each Pocket_feature is a General_pocket, a Rectangular_closed_pocket, or a Rectangular_open_pocket.
The data associated with a Pocket_feature are the following:
The base_radius specifies a radius shape blend between a Pocket_feature and the surrounding surface at its base.
See pocket_feature to feature_parameter for the application assertion.
The base_radius need not be specified for a particular Pocket_feature.
The bottom_condition specifies the Pocket_bottom_condition or the Through_pocket_bottom_condition object that defines the type of the pocket bottom.
See pocket_feature to pocket_bottom_condition and pocket_feature to through_pocket_bottom_condition for the application assertions.
There shall be exactly one object that defines the bottom_condition for a Pocket_feature.
The boundary specifies the Profile_usage that provides the enclosing Profile for the Pocket_feature.
See pocket_feature to profile_usage for the application assertion.
The pocket_depth specifies the Linear_path that is used to sweep the Closed_profile.
See pocket_feature to linear_path for the application assertion.
The taper specifies an angular variation of the size of the Pocket_feature along the sweep path. The variation shall be specified either by an Angle_taper or by a Directed_taper.
See pocket_feature to angle_taper, pocket_feature to diameter_taper, and pocket_feature to directed_taper for the application assertions.
The taper need not be specified for a particular Pocket_feature.
If present, there shall be exactly one object that defines the taper for a Pocket_feature.
