Effectiveness of the 3D Software in pattern making and assembling the jackets for obese women using the Turkish method, through a comparison between the real and the 3D virtual methods, The research relied on the experimental approach, six different sizes for obese women jackets were selected and assembled by the Turkish pattern block-making method (Real method). In parallel, Gerber software was used to make the pattern block with CLO 3D software for Simulation (Virtual method). The Real and virtual methods for making the jacket were evaluated using a questionnaire by academic expertise. The results were statistically analyzed. It was found that there is no significant difference between the Real and virtual methods, and it was proved that the efficiency of the 3D garment software for obese women jackets, reduces the time and waste of fabric during the garment manufacturing process, and it can also be replaced in the future by the samples and rehearsal section in the garment field.
