Provides functions to build mechanical features. Mechanical features include ribs - protrusions and grooves (or slots) - depressions along planar (linear) surfaces or revolution surfaces. The semantics of mechanical features is built around giving thickness to a contour. This thickness can either be unilateral - on one side of the contour - or bilateral - on both sides. As in the semantics of form features, the thickness is defined by construction of shapes in specific contexts. The development contexts differ, however,in case of mechanical features. Here they include extrusion: More...

const TopTools_ListOfShape & | FacesForDraft () const |
Returns a list of the limiting and glueing faces generated by the feature. These faces did not originally exist in the basis shape. The list provides the information necessary for subsequent addition of a draft to a face. It may be an empty list. If a face has tangent edges, no draft is possible, and the tangent edges must subsequently be removed if you want to add a draft to the face. More... | |
const TopTools_ListOfShape & | NewEdges () const |
Returns a list of the limiting and glueing edges generated by the feature. These edges did not originally exist in the basis shape. The list provides the information necessary for subsequent addition of fillets. It may be an empty list. More... | |
const TopTools_ListOfShape & | TgtEdges () const |
Returns a list of the tangent edges among the limiting and glueing edges generated by the feature. These edges did not originally exist in the basis shape and are tangent to the face against which the feature is built. The list provides the information necessary for subsequent addition of fillets. It may be an empty list. If an edge is tangent, no fillet is possible, and the edge must subsequently be removed if you want to add a fillet. More... | |
