Abstract: CAD models especially surface models are basically not easy to design and edit with 2- D based interfaces due to their three dimensional nature. Many researchers have presented their work on techniques for deformation of CAD surface models. Achieving greater control on the shape of deformation of surface models is thus a need. Many techniques are numerically not that much efficient and deforming complex surface models in real time is thus a difficult task. An effort is made here to review papers based on deformation of CAD surface models critically and thus provide solution to these complex problem. In this context model gains specific importance as it not only help in learning the factors associated with it but also will provide a direction for improvements. This paper makes an attempt to study various techniques to deform surface model in real time. The primary aim of this paper is to understand and enhance the important aspects. Thirteen models are reviewed in this paper. Each of them is representative of a different conceptual view about deformations. The organization of this paper is as follows: initially after highlighting the need for the present study, a generalized framework of the study is presented. This is followed by a brief discussion and a critical appraisal. Finally the agenda for future research is spelt out.
