Summary0022766: Wrong results done by several algorithms for the case of intersection between a surface of revolution and a plane
DescriptionWrong results done by several algorithms for the case of intersection between a surface of revolution and a plane.
Source shapes are a couple of faces f1, f2.

Case 1.
Pure intersection between underlying surfaces s1, s2 (for f1, f2) does not work. (Exception)
--------------
Case 2.
The intersection between two faces produces 4 curves c_1, c_2, c_3, c_4.
c_1 - seems to be Ok;
c_2 - seems to have wrong derivative on the end with maximal value of the parameter;
c_3 - is BSplineCurve[Degree 1, 2 Poles, 2 Knots]. The two poles are equal 3D-points;
c_4 - the same as c_3;
-------------
Case 3.
 c_1 is the intesection curve between s1, s2;
 The 3D-points Pi [i=1,2...NbP] are taken from c_1 at different values of the parameter.
 The distances between points Pi [i=1,2...NbP] and s2 obtained by projection algorithm are wrong.
Steps To ReproduceUse the following commands to reproduce the problems:
#-------------------
#Case 1
restore f1
restore f2
mksurf s1 f1
mksurf s2 f2
intersect i s1 s2

#-------------------
#Case 2
restore f1
restore f2
bopcurves f1 f2

#-------------------
#Case 3
restore f1
restore f2
bopcurves f1 f2
mksurf s1 f1
mksurf s2 f2

Branch CR22766 is ready to review.
Note: correction is only to fix exeption (case 1 of bug)

One remark: Precision::IsInfinite(Real) makes Abs(Real) itself, so Abs(argument) is excessive.

The second part of this bug (case 2 and case 3) was moved for new issue: 0023948
so the subject of this issue is only case 1 - exception during intersection.
