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.
