The paper describes a new modeling method by which an object of a thin thickness can be modeled in an efficient way. In this study, a thin object, considered as a sheet model, is modeled by adding, cutting, and bending each sheet created interactively in the two dimensional working plane. Then the straight edges can be changed into curved ones for complicated shapes. Once a sheet model is completed, the corresponding solid is created automatically for a given thickness.
Compared to other solid modeling systems, the modeling method suggested in this study has the advantage of easy usage and short modeling time for sheet-like objects such as most plastic products.
