59-71. 1 Ruled Surfaces of Zero Total Curvature Cylindrical, conical, torse surfaces, a plane, and surfaces of polyhedrons are called surfaces of zero Gaussian curvature or developable surfaces. A surface is called a developable surface if it can be developed on a plane without any lap fold or break. During this process, the length of the curves and the angles between two curves belonging to the developable surface remain unchanged. Cylinders and cones are the simplest developable surfaces, being degenerate.
