Abstract: Considering the fact that the intelligent technology are not advanced when using CAD for developing paper pattern system,an automatic pattern design system characterized by being visual and easy to operate is proposed.It makes use of parameterized design principle and combines body shape features with structural characteristics.Simulation of garment structural lines,digital expression of the structure and description of specialist knowledge are completed by mathematical function analogue.Parameterized design governs the garment size systems,and design variation is executed by input of new parameters.This design method provides a technological basis for realization of an artificial intelligent paper pattern design revising system.
