class Loop2d from Partition
---Purpose: Builds the loops from a set of edges on a face.
-- It works in supposition that all constant edges
-- are split edges of an initialization face and all
-- section edges are new on the face
uses
Orientation from TopAbs,
Boolean from Standard,
Face from TopoDS,
Image from BRepAlgo,
Face from TopoDS,
Edge from TopoDS,
ListOfShape from TopTools,
DataMapOfShapeListOfShape from TopTools,
MapOfShape from TopTools
is
Create;
Init (me : in out; F : Face from TopoDS)
---Purpose: Init with <F> the set of edges must have
-- pcurves on <F>.
is static;
AddConstEdge (me : in out; E : Edge from TopoDS)
---Purpose: Add <E> as unique edge in the result.
is static;
AddSectionEdge (me : in out; E : Edge from TopoDS)
---Purpose: Add <E> as double edge in the result.
is static;
Perform(me : in out)
---Purpose: Make loops.
is static;
NewWires (me)
---Purpose: Returns the list of wires performed.
-- can be an empty list.
---C++: return const &
returns ListOfShape from TopTools;
WiresToFaces (me : in out; EdgeImage : Image from BRepAlgo)
---Purpose: Build faces from the wires result.
-- <EdgeImage> serves to find original edge by new
-- one.
is static;
NewFaces (me)
---Purpose: Returns the list of faces.
---Warning: The method <WiresToFaces> as to be called before.
-- can be an empty list.
---C++: return const &
returns ListOfShape from TopTools;
