基于AutoCAD参数化功能的A型裙样板自动化生成

为更好地实现AutoCAD参数化功能在服装行业大规模个性化制版中的应用,针对A型裙样板难以参数化的问题,采用单圆弧拟合腰围线、双圆弧拟合摆围线的方法,构建A型裙结构的参数化模型。通过对约束方法的分析比较,提出参数化约束原则,解决AutoCAD参数化功能应用时存在的运行缓慢、紊乱和卡死等问题。根据AutoCAD参数化功能特点,给出A型裙样板参数化设计方法,实现具备规格变化、摆围大小调整、摆围线形状变化、放缝、面料经向选择等功能的A型裙样板自动化生成。研究结果表明:基于AutoCAD参数化功能的A型裙参数化样板,操作简易直观,可显著减少制版时间,提高工作效率,满足服装个性化定制的快速制版要求。

Automatic generation of A-type skirt model based on AutoCAD parametric function

In order to better use AutoCAD parametric function for large-scale personalized plate making in the garment industry,a new method of fitting waist line with single arc and swing line with biarc is adopted aiming at problems in parameterizing A-type skirt pattern.Through analysis and comparison of constraint methods,the principle of parametric constraints proposed solved the problems when using AutoCAD parametric functions,such as slow operation,result disorder and system stuck.Using the parameterized function of AutoCAD,A-type skirt patterns can be achieved based on the automatically generated A-type skirt model,which had functions on specification alteration,bottom opening size adjustment,sweep shape change,doubling,and fabric radial selection.The results show parametric model of A-type skirt based on AutoCAD parametric function leads to simple operation and is intuitive,which significantly saves the model-making time,doubles the work efficiency,and meets the requirements for rapid plate-making of personalized clothing customization.
