SOME ASPECTS OF GEOMETRY OF THE SURFACES WITH SYSTEM OF PLANE COORDINATE LINES IN PLANES OF PENCIL

The article is considered the geometry of the surfaces with system of plane lines in the planes of pencil. There received the equation of the surface when parametric equation of directrix line is used and the pole of the surface is not coincided with the origin of coordinates.
