Q. Categorization of Geometric models?
Modern CAD systems define objects in 3-D. Thus, the designer can construct 3-D model of objects conveniently and store the database of the model in the computer. Geometric models can be classified into three types :
(i) Wire-frame model.
(ii) Surface model.
(iii) Solid model.
