A new garment cad for modern 2d/3d geometric modeling of wearing apparel

Development of a new cad system for garment design which aims at offering a modern and robust 2d/3d geometric modeling environment. The envisaged 2d/3d garment cad system will take full advantage of robust 3d geometric modeling and 3d body scan technology

The international garment industry has long been operating in a highly competitive environment, thus it relies heavily on computers and special Computer-Aided Design (CAD) software to increase design productivity and to efficiently support production processes. Current CAD systems in this sector are primarily 2D aiming at offering reliable tools to perform modelling operations related to 'Design', 'Grading', 'Detailing', and 'Layout'. The design component usually offers various tools that support multiple design-methods: free-hand design on the screen, digitizing/inputting and manipulating existing patterns, constructing new patterns, transformation of shapes, colour management, garment assembly, etc. Advanced systems even offer some 'simulation' and 'design interrogation' tools, e.g. stitch or weave simulation and curve-length verification. Garment CAD technology is irreplaceable when it comes to 'grading'; systems offer automatic grading to standard sizes and made-to-measure sizes, editing/manipulation of 'grade rules', interactive grading (if preferred), etc. Garment-CAD systems place a heavy emphasis on offering many 'detailing' tools to the user to enhance a pattern piece with curves, diagrams, zips, buttons, etc. Finally, individual patterns are assembled using the 'layout' component of the CAD system. Here, semiautomatic editing and manipulation tools are offered to correctly place patterns onto the marker. Although most of the current CAD systems are, to some degree, modularized, following the component-structure described above, their predominant characteristic is offering the user an increasing number of automatic or semiautomatic 'electronic versions' of standard manual techniques. Unlike current practices in mechanical and industrial CAD, where the user is exposed to the underlying geometric and information-modelling technologies, garment CAD views the user as incapable of dealing with core CAD methods, like curve/surface design, boolean operations, etc. This 'keep the atelier designer away from technology' philosophy is characterized by the following two major features: * CAD operations are (or at least are meant to be) "fully transparent", i.e. they involve no use of CAD concepts but rather they try to fully mimic manual methods. * All components of the CAD system are 2D. We feel that this strategy is no longer justifiable in view of (a) the overall sophistication and economic strength of many garment designers/manufacturers, and (b) the increasing robustness and user friendliness of core CAD technology. The above strategy of major garment-CAD companies has led to the current 'technological gap' between the garment industry and the research community, with the latter exploring new 3D modelling and "Virtual Fit" technologies that are clearly far off any manual garment-design method.
