Linear surface on a curve with a tangent to the surface is achieved by moving a segment, with the start vertex of the segment lying on the selected curve and the end vertex on the selected surface, provided that the segment touches the surface at the given point (i.e., the segment in the section belongs to the tangent to the intersection curve of the surface with the section plane). The plane of the section in each of its positions is perpendicular to the specified straight-line direction or curve.
