ISO 10303-214:2010(E)
A Rib_feature is a feature that is applied to solid parts to increase the stability of certain regions of a part.
EXAMPLE Figure 62 illustrates a Rib_feature.
A Rib_feature is a type of Process_feature_in_solid.
The data associated with a Rib_feature are the following:
The draft_taper specifies a Directed_taper that defines the value of the draft angle that is applied to the side walls of the Rib_feature and the draft direction.
See rib_feature to directed_taper for the application assertion.
The draft_taper need not be specified for a particular Rib_feature.
The fillet_radius specifies a radius shape blend between a Rib_feature and the surrounding faces.
NOTE If different fillets are required for the various intersection between the Rib_feature and the shape of the part, Transition_feature objects have to be applied.
See rib_feature to feature_parameter for the application assertion.
The fillet_radius need not be specified for a particular Rib_feature.
The rib_profile specifies the Open_profile_usage which references the Open_profile that is swept along the Path. The Open_profile is the cross section of the rib including the two sides and the connecting top part. It shall be shaped in a way that the two sides of the resulting Rib_feature are parallel (before the application of a Directed_taper).
See rib_feature to open_profile_usage for the application assertion.
The shoulder_radius specifies the blend radius at the shoulder of the Rib_feature.
See rib_feature to feature_parameter for the application assertion.
The shoulder_radius need not be specified for a particular Rib_feature.
The sweep_path specifies the Path along which the Open_profile is swept. The sweep process shall stop as soon as the added volume intersects the surfaces of the part.
See rib_feature to path for the application assertion.
