0024585: Wrong pcurve of the section curve

Browse Source 
PCurve is extended to surface boundary forcefully.
It is made by finding some additional points (if it is possibly).
"bopcurves" DRAW-command returns number of found 3D-curves and (as an option) 2D-curve (see help for more detail information).
