Range of changing of some analytic curves is computed by other methods. It allows computing face's boundaries with more precise. Tolerance was increased to provide successful work of some algorithms. Functions BRepOffsetAPI_MiddlePath::Build() and ApproxWithPCurves(...) (file IntTools_FaceFace.cxx) were changed according to new result of algorithm's work. It is possibly for "outboundaried faces" (see bug#23675) to compute incorrect UV-Bounds, when first parameter is more than last. To avoid it, extended control of computed bounds was added. Function for fail sameparameter fixing was added to HLRAppli_ReflectLines to avoid creation bad shapes after algorithm's work. In file ShapeFix_ComposeShell.cxx only text formatting was changed. Some test cases are changed according to their new behavior. Added test case bugs/moddata_3/bug23511

---Purpose: Computes the bounding box for a curve in 2d .
|
|
-- Functions to add a 2D curve to a bounding box.
|
|
-- The 2D curve is defined from a Geom2d curve.
|

|
|
---Purpose: Adds to the bounding box B the curve C
|
|
-- B is then enlarged by the tolerance value Tol.
|
|
-- Note: depending on the type of curve, one of the following
|
|
-- representations of the curve C is used to include it in the bounding box B:
|
|
-- - an exact representation if C is built from a line, a circle or a conic curve,
|
|
-- - the poles of the curve if C is built from a Bezier curve or a BSpline curve,
|
|
-- - if not, the points of an approximation of the curve C.
|
|
-- Warning
|
|
-- C is an adapted curve, that is, an object which is an interface between:
|
|
-- - the services provided by a 2D curve from the package Geom2d
|
|
-- - and those required of the curve by the computation algorithm.
|
|
-- The adapted curve is created in the following way:
|
|
-- Handle(Geom2d_Curve) mycurve = ...
|
|
-- ;
|
|
-- Geom2dAdaptor_Curve C(mycurve);
|
