0031463: Intersection curve is displaced
The intersection curve of two BSplineSurfaces is strangely displaced.
1) Extract the two BRep files from the zip
Use the draw commands to reproduce:
> pload ALL
> vinit
> restore "obj1.brep" obj1
> restore "obj2.brep" obj2
> bop obj1 obj2
> bopsection myIntersection
> vdisplay obj1
> vdisplay obj2
> vdisplay myIntersection
> vtop
> vfit

The myIntersection curve is displaced according to the expected

Eugeny,
bopcurves gives the right 1 curve, so, the problem is on the side of builder.
