We developed a pattern drafting computer program using a popular CAD program for the purpose of the automatic manufacturing and education based on the concept of the easy -order-system which can easily reflect body characteristics and design favors of individuals to the ready-made clothing. The programs were written in Auto LISP which can utilise most of frictions of the Auto CAD, and the result of the design for an full-pleated skirt was shown. Also, we devised an easy way to set the location of reference points by inputting of tangential angle only for the use of the cubic spline curve which can represent body shape very well. Finally, by marking down all of symbols needed in manufacturing process, we completed the automatic pattern drafting program to make it useful as an industrial pattern without any amendment or correction in cutting and sewing operation.

In the modern fashion industry, efficiency has been increasing thanks to development of computer graphics, IT technology, and digitalization. Unlike the past when fashion design heavily depended on handwork, digitalization of fashion industry makes fabrication time shorter and enables designers to adopt comprehensive expression, generating high value-added product. The Apparel CAD, an example of the digitalized fashion industry, has been developed from 2D system into a system providing 3D simulation. Digital clothing can be determined as an activity of designers using the tool in order to fabricate pattern and simulate its designed clothes in the virtual space of computer. In this study, physical properties of eight materials, which can be utilized on a par with current fashion trend, have been specified. For more sophisticated investigation, external appearance of the material was investigated by 3D scanning. In order to examine the physical properties of fabric specimens, KES(Kawabata Evaluation System) measurements and other physical property measurements were made. With the results, virtual material and clothes were simulated via CLO 3D, one of 3D apparel CAD systems. Then, virtual fabrics and clothes of similar types were generated and analyzed.

Knitwears it was only for the innerwear, but which has become more available for sportswear and highly valuable formal-dresses for women's apparel and is set a trend toward high value-added products worldwide. Also the industry connected knitwears is more widely applicative than woven industry and is running on the well founded basement for the small enterprises. This study notes that what problems are caused and which utilities can be expected when we design knitwears by Primavision and Texpia CAD system considered the programs for development of domestic knitwears industry. There are much various benefits for designing knitwears from CAD system as shortening working hours, convenience, accuracy, quality control and productivity. It doesn't depend on designer's technique, sense and experiences, but provides, through building the design accuracy, chance to have a precise communication with buyers to be satisfied with the multiplicity, uniqueness and high-quality resulting from reducing the mistake on the operation. But there are some problems for using CAD design system those are no selections for the form, type and thickness of the yarn. Even though it is knitted by the same gauge, the texture conditions show complete difference if the form and thickness is different with. The gauge control without regarding those ought to be improved and the yarn designing function should be appended like in a tektite design. And the CAD design system can not reflect the variables of operating knitting machine and needle. The CAD design system provides the manufacturers with merits those they can change the colors easily to select which one appeals to the customer and check the effects of producing and modeling on monitor. But, in the each producing progress, there are still problems to reduce the practical steps, so intensive care is required of each part.

This study tries to understand the characteristics of a man's clothes from the late 17th century to the early 18th century, held by the Ewha Womans University Museum. The author adopted the Assy CAD, an apparel CAD system developed by Assysit Company of Germany, in measuring clothes which is intended to solve the problems raised in the previous measurement of clothes, as well as in the making of patterns. The author used tracing paper to make copies of the curved parts, put them into the computer by digitiger, and made the patterns for more accurate restoration. Furthermore, the author compared Lee Hwang's with the contents of the related literature and excavated apparel from other tombs. As a result, Chopri among Lee Hwang's clothes, retained the typical characteristics of the mid-Chosun men's fashion in its ratio of bodice to skirt, form of sleeves, and size of breast- ties for fastening which appeared in the 17th century. Daechangeui and Jungchimak also were distinctive for Changot and the width of sleeves since the 17th century and were in wide use not only as the daily clothes but also as the shroud. These changes were brought about from the two wars which emphasized prestige and beauty of the clothes rather than their functions. As a result, Changeuis were used more widely, while Chopri which was used as the underwear of officials' uniform, was in decline.
