ReassignPCurve()¶ - Reassign edge pcurve lying on face <old> to another face <sub>. If edge has two pcurves on <old> face, only one of them will be reassigned, and other will left alone. Similarly, if edge already had a pcurve on face <sub>, it will have two pcurves on it. Returns True if succeeded, False if no pcurve lying on <old> found.

Apply()¶ - Applies the substitutions requests to a shape //! <until> gives the level of type until which requests are taken into account. For subshapes of the type <until> no rebuild and futher exploring are done. ACTUALLY, NOT IMPLEMENTED BELOW TopAbs_FACE //! <buildmode> says how to do on a SOLID,SHELL … if one of its sub-shapes has been changed: 0: at least one Replace or Remove -> COMPOUND, else as such 1: at least one Remove (Replace are ignored) -> COMPOUND 2: Replace and Remove are both ignored If Replace/Remove are ignored or absent, the result as same type as the starting shape

TopoDS_Shape* Applies the substitutions requests to a shape. //! <until> gives the level of type until which requests are taken into account. For subshapes of the type <until> no rebuild and futher exploring are done. //! NOTE: each subshape can be replaced by shape of the same type or by shape containing only shapes of that type (for example, TopoDS_Edge can be replaced by TopoDS_Edge, TopoDS_Wire or TopoDS_Compound containing TopoDS_Edges). If incompatible shape type is encountered, it is ignored and flag FAIL1 is set in Status.

CombineVertex()¶ - Combines new vertex from two others. This new one is the smallest vertex which comprises both of the source vertices. The function takes into account the positions and tolerances of the source vertices. The tolerance of the new vertex will be equal to the minimal tolerance that is required to comprise source vertices multiplied by tolFactor (in order to avoid errors because of discreteness of calculations).
