Abstract: This study sets fast pattern generating as the goal and takes blouse pattern as the research object, and it puts forward the parameterized design method based on numerical geometric constrains, obtains the constraints for each part of the blouse pattern, consequently parameterizes the pattern, and a complete parametric constrains database and rule library for blouse pattern are set up, laying a data foundation for automatic generation and interactive modification of blouse pattern.

Key words: pattern; automatic generation; blouse; parameterization; database
