Computer-aided design (CAD) is one of the actual trends of technologicalpre-production development which provides high quality and efficiency of design projects. Designing of technological process(TP) assisted by CAD systems allows in a short time to perform preparatorystages before launching new models into production. A stage of technologicaldesign is a preparing of technological documentation which describes a processof a new model manufacturing. The input data for the item design will be: a technical sketch, adescription of the models appearance and a specification of the cuttingdetails.


It is known that text documentation resulted fromtraditional technological product design does not reveal the links betweenitems, equipment and definite elements of TP, which prevents us from developingof an efficient design of production. Therefore we developed a method for compositionof graphical documentation assisted by CAD which reveals external structure of TP of clothes manufacturing with the links extracting.


The main stages of clothes manufacturing TP are thefollowing: parts processing and their joining into a garment. The stage of partsprocessing assumes parallelism of details and units treatment. The garmentunits are separate parts of the garment according to construction andtechnological processing (front and back panels, collar and etc.). During thestage of parts processing each unit is made of one or several cut details whichprocessing can be composed from units processing. The unit is a complex part ofthe garment which is characterized by completeness of technological processing.The followings are determined as the units which can belong to any garmentdetails: pockets, fastenings, vents and openings.


During the stage of parts joining the garment details arejoined to each other. For example the constructive elements (CE) of clotheswith waistbands joining stage are side, step, middle cuts, top and hem cuts ofthe product. Determination of the CE sequence at the stage of joining requires analysisof all elements links, and this considerably complicates the process of thetechnological sequence formation. Existence of some model-constructive featuresin the garment details changes the sequence of CE processing. Thus, forexample, the design of trousers waistband determines theprocessing sequence at the stages of middle, side and top cuts processing.
