Abstract

Grading is a crucial task for pattern makers, involving increasing or decreasing the original pattern according to body measurements to produce different sizes for clothing production. Computer grading systems have advanced significantly; CLO 3D is one such system that provides distinctive grading features, including auto-grading and edit grading, which improve industrial efficiency and productivity. The auto-grading technique creates new patterns in different sizes based on existing patterns, reducing errors and eliminating the necessity for manual grading. This study employs the auto-grading features of CLO 3D in grading complex patterns. Besides, it ensures that the various graded sizes fit and conform to the body. Furthermore, evaluate the fit of the graded patterns for each style on the 3D parametric virtual mannequin using the fit maps supplied by the CLO 3D program.
The basic bodice block pattern was drafted and graded with the CLO 3D auto-grading tool, then the fit of the graded pattern was evaluated with fit maps on a 3D parametric virtual mannequin. Therefore, two complex women's styles were selected and drafted using the CLO 3D program with size XS. The auto-grading technique was applied to the style's patterns with the sizes (S-M-L). The graded pattern fit was then evaluated with fit maps on a 3D parametric virtual mannequin. The results indicate that the auto-grading tool within the CLO 3D program has proven highly effective in grading complex styles, considering virtual Evaluation using the fit maps method. This tool facilitates the automatic grading of such complex styles, achieving accurate and well-fitted outcomes.
