Geom2dGcc_Circ2d2TanRad
(*args)¶ Bases:
object
Parameters: Return type: Return type:  These constructors create one or more 2D circles of radius Radius either  tangential to the 2 curves Qualified1 and Qualified2, or  tangential to the curve Qualified1 and passing through the point Point, or  passing through two points Point1 and Point2. Tolerance is a tolerance criterion used by the algorithm to find a solution when, mathematically, the problem posed does not have a solution, but where there is numeric uncertainty attached to the arguments. For example, take two circles C1 and C2, such that C2 is inside C1, and almost tangential to C1. There is, in fact, no point of intersection between C1 and C2. You now want to find a circle of radius R (smaller than the radius of C2), which is tangential to C1 and C2, and inside these two circles: a pure mathematical resolution will not find a solution. This is where the tolerance criterion is used: the algorithm considers that C1 and C2 are tangential if the shortest distance between these two circles is less than or equal to Tolerance. Thus, a solution is found by the algorithm. Exceptions GccEnt_BadQualifier if a qualifier is inconsistent with the argument it qualifies (for example, enclosing for a line). Standard_NegativeValue if Radius is negative.
Parameters: Return type: 
IsDone
()¶  This method returns True if the algorithm succeeded. Note: IsDone protects against a failure arising from a more internal intersection algorithm, which has reached its numeric limits.
Return type: bool

IsTheSame1
()¶  Returns true if the solution of index Index and, respectively, the first or second argument of this algorithm are the same (i.e. there are 2 identical circles). If Rarg is the radius of the first or second argument, Rsol is the radius of the solution and dist is the distance between the two centers, we consider the two circles to be identical if Rarg  Rsol and dist are less than or equal to the tolerance criterion given at the time of construction of this algorithm. OutOfRange is raised if Index is greater than the number of solutions. notDone is raised if the construction algorithm did not succeed.
Parameters: Index (int) – Return type: bool

IsTheSame2
()¶  Returns true if the solution of index Index and, respectively, the first or second argument of this algorithm are the same (i.e. there are 2 identical circles). If Rarg is the radius of the first or second argument, Rsol is the radius of the solution and dist is the distance between the two centers, we consider the two circles to be identical if Rarg  Rsol and dist are less than or equal to the tolerance criterion given at the time of construction of this algorithm.

Warning This indexing simply provides a means of consulting the solutions. The index values are not associated with these solutions outside the context of the algorithm object. Exceptions Standard_OutOfRange if Index is less than zero or greater than the number of solutions computed by this algorithm. StdFail_NotDone if the construction fails.
Parameters: Index (int) – Return type: gp_Circ2d

Parameters: Return type:  Constructs one or more 2D circles tangential to two curves Qualified1 and Qualified2 and passing through the point Point, where Param1 and Param2 are used, respectively, as the initial values of the parameters on Qualified1 and Qualified2 of the tangency point between this argument and the solution sought, if the algorithm chooses an iterative method to find the solution (i.e. if either Qualified1 or Qualified2 is more complex than a line or a circle).

Tolerance is a tolerance criterion used by the algorithm to find a solution when, mathematically, the problem posed does not have a solution, but where there is numeric uncertainty attached to the arguments.

()¶  Returns true if the solution is unqualified and false in the other cases.
Return type: bool

Qualified
()¶  Returns a 2D curve to which the qualifier is assigned. Warning The returned curve is an adapted curve, i.e. an object which is an interface between:  the services provided by a 2D curve from the package Geom2d,  and those required on the curve by a computation algorithm. The Geom2d curve on which the adapted curve is based can be obtained in the following way: myQualifiedCurve = ... ; Geom2dAdaptor_Curve myAdaptedCurve = myQualifiedCurve.Qualified(); Handle_Geom2d_Curve = myAdaptedCurve.Curve();
Return type: Geom2dAdaptor_Curve

Qualifier
()¶  Returns  the qualifier of this qualified curve if it is enclosing, enclosed or outside, or  GccEnt_noqualifier if it is unqualified.
Return type: GccEnt_Position

Enclosed
(*args)¶  Constructs such a qualified curve that the solution computed by a construction algorithm using the qualified curve is enclosed by the curve. Warning Obj is an adapted curve, i.e. an object which is an interface between:  the services provided by a 2D curve from the package Geom2d,  and those required on the curve by a computation algorithm. The adapted curve is created in the following way: Handle_Geom2d_Curve mycurve = ... ; Geom2dAdaptor_Curve Obj ( mycurve ) ; The qualified curve is then constructed with this object: Geom2dGcc_QualifiedCurve myQCurve = Geom2dGcc::Enclosed(Obj);
Parameters: Obj (Geom2dAdaptor_Curve &) – Return type: Geom2dGcc_QualifiedCurve

static

(*args)¶  Constructs such a qualified curve that the solution computed by a construction algorithm using the qualified curve encloses the curve. Warning Obj is an adapted curve, i.e. an object which is an interface between:  the services provided by a 2D curve from the package Geom2d,  and those required on the curve by a computation algorithm. The adapted curve is created in the following way: Handle_Geom2d_Curve mycurve = ... ; Geom2dAdaptor_Curve Obj ( mycurve ) ; The qualified curve is then constructed with this object: Geom2dGcc_QualifiedCurve myQCurve = Geom2dGcc::Enclosing(Obj);

Outside
(*args)¶  Constructs such a qualified curve that the solution computed by a construction algorithm using the qualified curve and the curve are external to one another. Warning Obj is an adapted curve, i.e. an object which is an interface between:  the services provided by a 2D curve from the package Geom2d,  and those required on the curve by a computation algorithm. The adapted curve is created in the following way: Handle_Geom2d_Curve mycurve = ... ; Geom2dAdaptor_Curve Obj ( mycurve ) ; The qualified curve is then constructed with this object: Geom2dGcc_QualifiedCurve myQCurve = Geom2dGcc::Outside(Obj);
Parameters: Obj (Geom2dAdaptor_Curve &) – Return type: Geom2dGcc_QualifiedCurve

static
Unqualified
(*args)¶  Constructs such a qualified curve that the relative position of the solution computed by a construction algorithm using the qualified curve to the circle or line is not qualified, i.e. all solutions apply. Warning Obj is an adapted curve, i.e. an object which is an interface between:  the services provided by a 2D curve from the package Geom2d,  and those required on the curve by a computation algorithm. The adapted curve is created in the following way: Handle_Geom2d_Curve mycurve = ... ; Geom2dAdaptor_Curve Obj ( mycurve ) ; The qualified curve is then constructed with this object: Geom2dGcc_QualifiedCurve myQCurve = Geom2dGcc::Unqualified(Obj);
Parameters: Obj (Geom2dAdaptor_Curve &) – Return type: Geom2dGcc_QualifiedCurve
