【摘要】 提出了一种适用于二维CAD软件的多明细表实现方案,该方案具有在一张CAD图纸中绘制多张装配图且每张装配图具有独立的明细表功能。采用"观察者-目标"模式对各明细表相关对象进行组织,实现零部件信息与具体图形表达的分离,减少了数据冗余,降低了对象耦合度,简化了数据的组织与提取,同时支持明细表的智能化修改和更新。实际应用表明,该方案提高了工程人员的设计效率,减少了错误的发生。更多还原

【Abstract】 A solution which supported multiple parts lists for two-dimensional CAD software was present.In the solution,multiple assembly drawings were supported in a CAD drawing,and each of them had independent parts list.With organizing the parts list related objects by "observer-subject" mode,the parts information and the graphic components were separated,data redundancy and object coupling were reduced,and the organization and retrieval of data were simplified.At the same time,intelligent modification and data update were supported.The applications show that the design efficiency for assembly body is improved by the solution,and the incidence of errors is reduced.更多还原
