Abstract: The current issue that autogenerated basic viewgraph of fullscale mockup were faced in AutoCAD was analyzed, which proposed to calculate the size of entity based on the features of fullscale mockup. This new methodology provided the solution of that old model that was not capable of define the size of entity issue which caused autopositioning problem between basis viewgraphs. It also offered a brand new technique to automatically generate basic viewgraph of fullscale mockup, which was benefited from VisualLISP coding application.

摘要： 分析了在 A u t o CAD中实现实体模型自动生成基本视图存在的问题, 提出了利用实体模型特性来确定实体外观尺寸的方法, 有效地解决了在 A u t o CAD中由于不能通过实体访问确定实体模型的外观尺寸, 从而导致无法实现基本视图间自动定位的问题。为实现在 A u t o CAD中由实体模型自动生成基本视图提供了一种新方法, 利用 V i s u a l L I S P语言编程自动生成了基本视图。
