OCC.Geom2dGcc module¶

Purpose: The Geom2dGcc package describes qualified 2Dcurves used in the construction of constrained geometricobjects by an algorithm provided by the Geom2dGcc package.A qualified 2D curve is a curve with a qualifier whichspecifies whether the solution of a constructionalgorithm using the qualified curve (as an argument):- encloses the curve, or- is enclosed by the curve, or- is built so that both the curve and this solution are external to one another, or- is undefined (all solutions apply).These package methods provide simpler functions to construct a qualified curve.Note: the interior of a curve is defined as the left-handside of the curve in relation to its orientation.

class Geom2dGcc_Circ2d2TanRad(*args)¶

Bases: object

Parameters:	Qualified1 (Geom2dGcc_QualifiedCurve &) – Qualified2 (Geom2dGcc_QualifiedCurve &) – Radius (float) – Tolerance (float) – Qualified1 – Point (Handle_Geom2d_Point &) – Radius – Tolerance –
Return type:	None
Return type:	None

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:	Point1 (Handle_Geom2d_Point &) – Point2 (Handle_Geom2d_Point &) – Radius (float) – Tolerance (float) –

Constructs one or more 2D circles tangential to the curve Qualified1 and passing through two points Point1 and Point2, where Param1 is used as the initial value of the parameter on Qualified1 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 Qualified1 is more complex than a line or a circle)

Parameters:	Qualified1 (Geom2dGcc_QualifiedCurve &) – Point1 (Handle_Geom2d_Point &) – Point2 (Handle_Geom2d_Point &) – Tolerance (float) – Param1 (float) –
Return type:	None

Constructs one or more 2D circles passing through three points Point1, Point2 and Point3. 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; and - a circle C3 outside C1. You now want to find a circle which is tangential to C1, C2 and C3: 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, the algorithm finds a solution. Warning An iterative algorithm is used if Qualified1, Qualified2 or Qualified3 is more complex than a line or a circle. In such cases, the algorithm constructs only one solution. Exceptions GccEnt_BadQualifier if a qualifier is inconsistent with the argument it qualifies (for example, enclosing for a line).
