1. Modify method IntPatch_ALineToWLine::MakeWLine: add correction of end points of each line on 2 surfaces if an end point is a pole on a surface. 2. Modify method IntPatch_WLine::ComputeVertexParameters: adjust a point on curve to corresponding vertex the following way: set 3D point as the point of the vertex and 2D points as the points of the point on curve.
