Summary0026777: Incorrect result of intersection part of bsection operation
DescriptionTest case "boolean bsection M3".

While calling "bsection" command we obtain wrong 3D-curve (see attached archive "bsection curves" - curve c2 has bent).

Attention:
Result of "bopcurves" operation produces curves, which seem to be valid.

Therefore, use modified command

   bopcurves a_1 a_2 -2d -p 0.20639206339545224 0.69260832843385300 0.0 0.017002507022347624

for reproducing problems (this option was entered to the fix for 26841 issue).
Steps To Reproducetest boolean bsection M3

with specify break point in method: BOPAlgo_PaveFiller::PerformFF() (BOPAlgo_PaveFiller_6.cxx):

for (i=1; i<=aNbCurves; ++i) {
....
const Handle(Geom_Curve)& aC3D= aIC.Curve();
....
}

(line 317 on IR-2015-10-08). See obtained 3D-curves.

              OR

bopcurves a_1 a_2 -2d -p 0.20639206339545224 0.69260832843385300 0.0 0.017002507022347624
Additional information
and documentation updates		The reason of different result between intersection part of "bsection" and "bopcurves" command is in adding additional start point in Walking-line (see BOPAlgo_PaveFiller::PerformFF(), "aFaceFace.SetList(aListOfPnts);", line 245 on IR-2015-10-08) during "bsection".

Dear Bugmaster,

Corresponding test case (boolean bsection M3) has been amended (in order to make possibility to detect this problem in the future) and pushed to the CR26841* branch.

The result of testing changed case is OK (see message 0026841:0049208).
