Constructs a surface approximation framework defined by.

• the conic Surf
• the tolerance value Tol3d
• the degree of continuity UContinuity, VContinuity in the directions of the U and V parameters
• the highest degree MaxDegU, MaxDegV which the polynomial defining the BSpline curve may have in the directions of the U and V parameters
• the maximum number of segments MaxSegments allowed in the resulting BSpline curve
• the index of precision PrecisCode.
