Computer Parametrization of Men's Trousers Pattern

The paper presents the research results of computer-aided construction and 3D clothing simulation in order to develop a computer-based parametric pattern of men’s trousers suitable for adjustments according to different figures and statures. At first, using a 3D body scanner, scanning and determining anthropometric body characteristics was performed on 50 male test subjects of a defined age group. Based on the detailed analysis of the obtained anthropometric data, five test body models of different figures and statures were selected from the complete test sample, on which the verification of a parametric trousers pattern was performed. The construction and grading of the basic trousers pattern was performed using the 2D/3D system for computer- aided construction and simulation of clothing, and selected 3D scanned body models were implemented in the 3D CAD system. The most complex part of the research included finding mathematical expressions for the calculation of segment adjustments on each cutting part, where it is necessary to ensure that in case of the modification of a particular cutting part all corresponding cutting parts are changed by the same amount or by the specific coefficient of proportionality. By application of defined mathematical expressions in the computer program and by defining additional pattern preparation elements, 2D cutting parts were transformed from vector into parametric form that enables simultaneous changes in several corresponding segments of cutting parts. Finally, a developed 2D parametric garment pattern was tested with the computer-assisted adjustment of the pattern for each individual test subject and 3D garment simulations of selected 3D body models with different anthropometric characteristics were performed.
