class Loop from BRepAlgo
---Purpose: Builds the loops from a set of edges on a face.
uses
Face from TopoDS,
Edge from TopoDS,
ListOfShape from TopTools,
DataMapOfShapeListOfShape from TopTools,
DataMapOfShapeShape 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;
AddEdge (me : in out; E : in out Edge from TopoDS;
LV : ListOfShape from TopTools)
---Purpose: Add E with <LV>. <E> will be copied and trim
-- by vertices in <LV>.
is static;
AddConstEdge (me : in out; E : Edge from TopoDS)
---Purpose: Add <E> as const edge, E can be in the result.
is static;
AddConstEdges (me : in out; LE : ListOfShape from TopTools)
---Purpose: Add <LE> as a set of const edges.
is static;
Perform(me : in out)
---Purpose: Make loops.
is static;
CutEdge(me;
E : Edge from TopoDS;
VonE : ListOfShape from TopTools;
NE : in out ListOfShape from TopTools)
---Purpose: Cut the edge <E> in several edges <NE> on the
-- vertices<VonE>.
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)
---Purpose: Build faces from the wires result.
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;
NewEdges (me ; E : Edge from TopoDS)
---Purpose: Returns the list of new edges built from an edge <E>
-- it can be an empty list.
---C++: return const &
returns ListOfShape from TopTools;
GetVerticesForSubstitute (me; VerVerMap: out DataMapOfShapeShape from TopTools);
---Purpose: Returns the datamap of vertices with their substitutes.
VerticesForSubstitute (me : in out; VerVerMap: in out DataMapOfShapeShape from TopTools);
---Purpose:
fields
myFace : Face from TopoDS;
myConstEdges : ListOfShape from TopTools;
myVerOnEdges : DataMapOfShapeListOfShape from TopTools;
myNewWires : ListOfShape from TopTools;
