class Tools from IntTools
---Purpose:
--- The class contains handy static functions
--- dealing with the geometry and topology.
uses
Shape from TopoDS,

State from TopAbs
is
ComputeVV (myclass;V1,V2:Vertex from TopoDS)
returns Integer from Standard;
---Purpose:
--- Computes distance between vertex V1 and vertex V2,
--- if the distance is less than sum of vertex tolerances
--- returns zero,
--- otherwise returns negative value
---
HasInternalEdge (myclass;
aW: Wire from TopoDS)
returns Boolean from Standard;
---Purpose:
--- Returns True if wire aW contains edges
--- with INTERNAL orientation
---
MakeFaceFromWireAndFace (myclass;
aW: Wire from TopoDS;
aF: Face from TopoDS;
aFNew:out Face from TopoDS);
---Purpose:
--- Build a face based on surface of given face aF
--- and bounded by wire aW
---
ClassifyPointByFace (myclass;
aF: Face from TopoDS;
P: Pnt2d from gp)
returns State from TopAbs;
---Purpose:
---
---
IsVertex (myclass; E: Edge from TopoDS;
t: Real from Standard)
returns Boolean from Standard;
---Purpose:
--- Computes square distance between a point on the edge E
--- corresponded to parameter t and vertices of edge E.
--- Returns True if this distance is less than square
--- tolerance of vertex, otherwise returns false.
---
IsVertex (myclass; E: Edge from TopoDS;
V: Vertex from TopoDS;
t: Real from Standard)
returns Boolean from Standard;
---Purpose:
--- Returns True if square distance between vertex V
--- and a point on the edge E corresponded to parameter t
--- is less than square tolerance of V
---
IsVertex (myclass; aCmnPrt: CommonPrt from IntTools)
returns Boolean from Standard;
---Purpose:
--- Returns True if IsVertx for middle parameter of fist range
--- and first edge returns True
--- and if IsVertex for middle parameter of second range and
--- second range returns True,
--- otherwise returns False
---
IsMiddlePointsEqual(myclass;
E1: Edge from TopoDS;
E2: Edge from TopoDS)
returns Boolean from Standard;
---Purpose:
--- Gets boundary of parameters of E1 and E2.
--- Computes 3d points on each corresponded to average parameters.
--- Returns True if distance between computed points is less than
--- sum of edge tolerance, otherwise returns False.
---
IsVertex (myclass;
aP : Pnt from gp;
aTolPV: Real from Standard;
aV: Vertex from TopoDS)
returns Boolean from Standard;
---Purpose:
--- Returns True if the distance between point aP and
--- vertex aV is less or equal to sum of aTolPV and
--- vertex tolerance, otherwise returns False
---
IntermediatePoint (myclass;
aFirst: Real from Standard;
aLast : Real from Standard)
returns Real from Standard;
---Purpose:
--- Returns some value between aFirst and aLast
---
SplitCurve (myclass;
aC : Curve from IntTools;
aS :out SequenceOfCurves from IntTools)
returns Integer from Standard;
---Purpose:
--- Split aC by average parameter if aC is closed in 3D.
--- Returns positive value if splitting has been done,
--- otherwise returns zero.
---
RejectLines(myclass;
aSIn: SequenceOfCurves from IntTools;
aSOut:out SequenceOfCurves from IntTools);
---Purpose:
--- Puts curves from aSIn to aSOut except those curves that
--- are coincide with first curve from aSIn.
---
IsDirsCoinside (myclass;
D1:Dir from gp;
D2:Dir from gp)
returns Boolean from Standard;
---Purpose:
--- Returns True if D1 and D2 coinside
---
IsDirsCoinside (myclass;
D1 :Dir from gp;
D2 :Dir from gp;
aTol:Real from Standard)
returns Boolean from Standard;
---Purpose:
--- Returns True if D1 and D2 coinside with given tolerance
---
IsClosed (myclass;
aC : Curve from Geom)
returns Boolean from Standard;
---Purpose:
--- Returns True if aC is BoundedCurve from Geom and
--- the distance between first point
--- of the curve aC and last point
--- is less than 1.e-12
---
CurveTolerance(myclass;
aC : Curve from Geom;
aTolBase : Real from Standard)
returns Real from Standard;
---Purpose:
--- Returns adaptive tolerance for given aTolBase
--- if aC is trimmed curve and basis curve is parabola,
--- otherwise returns value of aTolBase
