33 | //! One of the most significant aspects |
34 | //! of BRepFeat functionality is the use of local operations as opposed |
35 | //! to global ones. In a global operation, you would first |
36 | //! construct a form of the type you wanted in your final feature, and |
37 | //! then remove matter so that it could fit into your initial basis object. |
38 | //! In a local operation, however, you specify the domain of the feature |
39 | //! construction with aspects of the shape on which the feature is being |
40 | //! created. These semantics are expressed in terms of a member |
41 | //! shape of the basis shape from which - or up to which - matter will be |
42 | //! added or removed. As a result, local operations make calculations |
43 | //! simpler and faster than global operations. |
44 | //! Glueing uses wires or edges of a face in the basis shape. These are |
45 | //! to become a part of the feature. They are first cut out and then |
46 | //! projected to a plane outside or inside the basis shape. By |
47 | //! rebuilding the initial shape incorporating the edges and the |
48 | //! faces of the tool, protrusion features can be constructed. |
