Basing on a literature study and a systematic analysis of the structure of complicated objects, the paper justifies the necessity to design clothing in 3D computer systems and gives suggestions on using anthropometrical data in 3D clothing designing, identifies 2D and 3D designing types. A structural scheme of the production process, identifying the processes of typal production with the goal to determine the mutual relationship of the production preparation processes and the structure of the informative and software means, has been developed; it has been concluded that no matter what level CAD/CAM system is used, their usage provides a faster development of the product and shortens the working process. A complete 3D designing process would exclude different working stages connected with constructing and constructive modelling, 3D imitation and creation of a virtual prototype.
