조형과 3D CAD 원리를 응용하는 디자인 스케치

Design sketches acquire expressive ability to improve visual presentation considering creative ideas and formative. It is necessary to educate designers to design sketches based on aesthetic standards through formative design. This is why we need to understand the principles and elements of molding. The composition of the form was based on the screen composition of Lupines. The composition of the gypsum sketch, the jokes of ink, and the composition of the margins were presented. 3D CAD, which is increasing in design work, has a very important role in designing and expressing to improve the sketching ability of designers. The reason is that we need to constantly practice the process of seeing things → understanding → imagining → expressing. The process by which a designer sees and understands objects is based on the principle of a two-dimensional three-sided view. If you understand it, you will be able to imagine various forms of objects through 3D perspective and express them in sketches. Also, if you understand important techniques of 3D CAD, it will be a way to improve sketch expressiveness. We introduced the core principles of 3D CAD and how to apply sketches. Boolean Union, boolean union, difference, revolve, Sweep 2 Rail, Offset Surface, Extrude. Also, the case is presented as a sketch expression that understands the elements of 3D CAD. As a result, the drawing method of sketch considering modeling and 3D CAD elements and the modeling analysis of screen are presented together. Through this, it is possible to improve the sketching ability through the fusion of designing and CAD of the designer, and expansion of thinking centered on the design process will be achieved.
