Advantage of wire-frame modeling:

The main advantage of wire-frame modeling is its ease in construction of a model. So, it does not needs as much computer memory and time as does surface or solid modeling. But, the user time required preparing and/or input data is substantial and enhance rapidly with the difficulty of the object being modeled. Wire-frame models build the basis for surface models. Most active surface algorithms need wire-frame entities to produce surfaces. Finally, the CPU time needed to retrieve, edit, or update a wire-frame model is small compared to or solid or surface models usually.
