| Summary: | Designing 3-dimensional objects are important in order to meet the customers’ need. There are many objects that have been created and used in for various purposes such as products packaging, decorations and others. This paper focuses on designing 3-dimensional symmetrical objects which is a bottle design. The shape and configuration are significant for showcasing systems. The shape, size and shade of the 3-dimensional symmetrical objects are additionally influencing to advertising procedures. The design was produced by using combination methods of cubic Bezier and Trigonometry Bezier with a shape parameter with the Rotational Sweep Surface method. In this paper, the manipulation of the design was made based on the properties of both curves that is used to produce 2-dimensional designs. The designs were focused on the manipulation of control points and the value of shape parameter. After the manipulation stage, the 2-dimensional designs of two methods were converted into 3-dimensional design using the Rotational Sweep Surface method. After that, the best design was chosen after the manipulated stage. The best designs were chosen based on the simpler method in designing the variety shapes of bottle that can satisfy the consumers’ needs. Based on the result, it is shown that Trigonometry Bezier with a shape parameter is the best method to be used than Cubic Bezier Curve. © 2019, World Academy of Research in Science and Engineering.
