What is 3D wireframe and surface Modelling?

Three types of 3D modeling are supported: wireframe, surface, and solid. Each type has its own creation and editing techniques. A wireframe model is a skeletal description of a 3D object. There are no surfaces in a wireframe model; it consists only of points, lines, and curves that describe the edges of the object.
