Accepts min & max parameters -- to construct the face's bounds. Also accepts tolerance value (TolDegen) -- for resolution of degenerated edges. ---Level: Public returns MakeFace from BRepLib; ---------------------------------------------- -- From a wire ---------------------------------------------- Create(W : Wire from TopoDS; OnlyPlane : Boolean from Standard = Standard_False) ---Purpose: Find a surface from the wire and make a face. -- if is true, the computed surface will be -- a plane. If it is not possible to find a plane, the -- flag NotDone will be set. ---Level: Public returns MakeFace from BRepLib; ---------------------------------------------- -- From a surface and a wire ---------------------------------------------- Create(P : Pln from gp; W : Wire from TopoDS; Inside : Boolean = Standard_True) ---Purpose: Make a face from a plane and a wire. ---Level: Public returns MakeFace from BRepLib; Create(C : Cylinder from gp; W : Wire from TopoDS; Inside : Boolean = Standard_True) ---Purpose: Make a face from a cylinder and a wire. ---Level: Public returns MakeFace from BRepLib; Create(C : Cone from gp; W : Wire from TopoDS; Inside : Boolean = Standard_True) ---Purpose: Make a face from a cone and a wire. ---Level: Public returns MakeFace from BRepLib; Create(S : Sphere from gp; W : Wire from TopoDS; Inside : Boolean = Standard_True) ---Purpose: Make a face from a sphere and a wire. ---Level: Public returns MakeFace from BRepLib; Create(C : Torus from gp; W : Wire from TopoDS; Inside : Boolean = Standard_True) ---Purpose: Make a face from a torus and a wire. ---Level: Public returns MakeFace from BRepLib; Create(S : Surface from Geom; W : Wire from TopoDS; Inside : Boolean = Standard_True) ---Purpose: Make a face from a Surface and a wire. ---Level: Public returns MakeFace from BRepLib; ---------------------------------------------- -- From face and wire. ---------------------------------------------- Create(F : Face from TopoDS; W : Wire from TopoDS) ---Purpose: Adds the wire in the face ---Level: Public returns MakeFace from BRepLib; ---------------------------------------------- -- Auxiliary methods ---------------------------------------------- Init(me : in out; F : Face from TopoDS) ---Purpose: Load the face. ---Level: Public is static; Init(me : in out; S : Surface from Geom; Bound : Boolean; TolDegen : Real) ---Purpose: Creates the face from the surface. If Bound is -- True a wire is made from the natural bounds. -- Accepts tolerance value (TolDegen) for resolution -- of degenerated edges. ---Level: Public is static; Init(me : in out; S : Surface from Geom; UMin, UMax, VMin, VMax, TolDegen : Real) ---Purpose: Creates the face from the surface and the min-max -- values. Accepts tolerance value (TolDegen) for resolution -- of degenerated edges. ---Level: Public is static; Add(me : in out; W : Wire from TopoDS) ---Purpose: Adds the wire in the current face. ---Level: Public is static; ---------------------------------------------- -- Auxiliary methods ---------------------------------------------- CheckInside(me : in out) ---Purpose: Reorient the current face if the boundary is not -- finite. ---Level: Public is static private; ---------------------------------------------- -- Results ---------------------------------------------- Error(me) returns FaceError from BRepLib ---Level: Public is static; Face(me) returns Face from TopoDS ---Purpose: Returns the new face. -- ---C++: return const & ---C++: alias "Standard_EXPORT operator TopoDS_Face() const;" ---Level: Public raises NotDone from StdFail is static; fields myError : FaceError from BRepLib; end MakeFace;
