Milestone in the garment design is basic constructiondevelopment, because it defines garment silhouette, contouring degree and fitquality. Though quality fit surveillance of basic construction islabour-intensive process. That's why at the modern CAD system marketthere is a necessity of creation of cheap and rather accuracy subsystem of3dimensiional dummy development with ability of virtual fit of designed bymodeler garments. This problem decision has been already reflected in therange of CAD programs. However, methods of definition of graphic model ofperson's body usually don't serve the purpose of industrial garment design. Andgraphic model, by itself, as usual supports limited functional load.


Following image methods of graphic model of person's body inCAD can be singled out:


  • as virtual industrial dummy, constructed by main body's anthropomorphic measurements (main function of such dummy is 3dimensional garment visualization);
  • as dynamic dummy (such dummy is supposed for virtual demonstration of garment and usually doesn't correspond to body's anthropomorphic measurements) ;
  • as virtual model, resulted by scanning particular body method (function of such dummy is virtual fitting) (this dummies are not used for the industrial purposes because of high costs of hardware).


Function of construction of only separate parts of body'sgraphic model that is realized in modern CAD, limits scope of functions solvedby the means of automated system. Nowadays, development of 3D subsystem<Eleandr-Cad> at the Garment Technology department of Moscow State Universityof Design and Technology takes place. It permits the use of 3dimensional spaceat different stages of new garment design. Also in the subsystem wasimplemented ability to define bodys graphic model as interrelated parametricaldisplay of:


  • stylized model (for artistic sketch of the model designs)
  • model of industrial dummy (for development of technical design of new garments)
  • model of individual dummy (for virtual fitting of particular customer's figure)
  • dynamic dummy (for quality and comfort assessment)


For construction of graphic model of person's body 32 mainbody's anthropomorphic measurements and 342 additional measurements are used. Useof the 3d subsystem <Eleandr-Cad> will increase industrial efficiencysignificantly. Ability of object visualization, and wide set of tools for workwith 2- and 3-dimensional object models helps to simplify modeler's work to itslowest terms. And also it increases its efficiency due to the pattern quality improvementand the end product as a result.
