class FaceBuilder from BOP
---Purpose:
--- The algorithm to construct Faces from a WireEdgeSet
---
uses
Shape from TopoDS,
Face from TopoDS,
Wire from TopoDS,
Edge from TopoDS,
Vertex from TopoDS,
ListOfShape from TopTools,
SequenceOfInteger from TColStd,
LoopSet from BOP,
BlockIterator from BOP,
BlockBuilder from BOP,
WireEdgeSet from BOP,
FaceAreaBuilder from BOP,
PWireEdgeSet from BOP
is
Create
returns FaceBuilder;
---Purpose:
--- Empty constructor;
---
Do(me :out;
aWES : WireEdgeSet from BOP;
aForceClass : Boolean from Standard =Standard_True);
---Purpose:
--- Launches the algorithm consisting of four steps
--- 1. Split the WES on wires
--- 2. Make Loops from wires
--- 3. Make Areas from Loops
--- 4. Make Faces from Areas
---
DoInternalEdges (me :out)
is private;
---Purpose:
--- Processes internal edges if they exists
---
BuildNewFaces (me :out)
is private;
---Purpose:
--- Make Faces from Areas
---
WES (me)
returns WireEdgeSet from BOP;
---C++: return const &
---Purpose:
--- Selector
---
NewFaces (me)
returns ListOfShape from TopTools;
---C++: return const &
---Purpose:
--- Selector
---
SetTreatment (me: out;
aTreatment: Integer from Standard);
---Purpose:
--- Modifier
--- 0 -Treat internal edges,
--- 1 -Do not treat internal edges
---
SetManifoldFlag(me: out;
aMFlag: Boolean from Standard);
---Purpose:
--- Modifier
---
SetTreatSDScales (me: out;
aTreatment: Integer from Standard);
---Purpose:
--- Modifier
--- 1 -Treat scale configured same domain faces,
--- 0 -Do not treat them.
---
ManifoldFlag(me)
returns Boolean from Standard;
---Purpose:
--- Selector
---
Treatment (me)
returns Integer from Standard;
---Purpose:
--- Selector
---
TreatSDScales (me)
returns Integer from Standard;
---Purpose:
--- Selector
---
---
---
--- Faces' iterator
---
InitFace(me:out)
returns Integer from Standard;
MoreFace(me)
returns Boolean from Standard;
NextFace(me:out);
---Purpose:
---
---
--- Wires' iterator
---
InitWire(me:out)
returns Integer from Standard;
MoreWire(me)
returns Boolean from Standard;
NextWire(me:out);
IsOldWire(me)
returns Boolean from Standard;
OldWire(me)
returns Shape from TopoDS;
---C++: return const &
Wire(me)
returns Wire from TopoDS;
---C++: return const &
---Purpose:
---
---
--- Edges' iterator
---
FindNextValidElement(me:out);
InitEdge(me:out)
returns Integer from Standard;
MoreEdge(me)
returns Boolean from Standard;
NextEdge(me : in out);
Edge(me)
returns Edge from TopoDS;
---C++: return const &
---Purpose:
---
MakeLoops(me :out;
SS :out WireEdgeSet from BOP)
is private;
---Purpose:
--- Make Loops from wires
---
SDScales(me :out)
is private;
---Purpose:
--- Treatment SD faces with a "scale"
---
fields
myFace : Face from TopoDS;
