4.2.454 Rib_feature

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:

4.2.454.1 draft_taper

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.

4.2.454.2 fillet_radius

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.

4.2.454.3 rib_profile

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.

4.2.454.4 shoulder_radius

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.

4.2.454.5 sweep_path

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.
