Provides general functions to build form features. //! Form features can be depressions or protrusions and include the following types: //! - Cylinder //! - Draft Prism //! - Prism //! - Revolved feature //! - Pipe //! In each case, you have a choice of operation type between the following: //! - removing matter (a Boolean cut: Fuse setting 0) //! - adding matter (Boolean fusion: Fuse setting 1) //! The semantics of form feature creation is based on the construction of shapes: //! - along a length //! - up to a limiting face //! - from a limiting face to a height //! - above and/or below a plane //! The shape defining construction of the feature can be either the //! supporting edge or the concerned area of a face. //! In case of the supporting edge, this contour can be attached to a //! face of the basis shape by binding. When the contour is bound to this //! face, the information that the contour will slide on the face //! becomes available to the relevant class methods. In case of the //! concerned area of a face, you could, for example, cut it out and //! move it to a different height which will define the limiting face of a //! protrusion or depression. //! Topological definition with local operations of this sort makes //! calculations simpler and faster than a global operation. The latter //! would entail a second phase of removing unwanted matter to get the same result. class BRepFeat_Form : public BRepBuilderAPI_MakeShape { public: DEFINE_STANDARD_ALLOC //! returns the list of generated Faces.
