| 摘 要： | 简单介绍了ＡｕｔｏＣＡＤ１２．０中实体数据库的结构形式及一般访问办法。以ＡｕｔｏＣＡＤ内嵌的编程语言ＡｕｔｏＬＩＳＰ实现了对封闭图形实体及节点的顺序提取，提出了一种简便、正确、可靠的提取尺寸实体文本数据的方法－尺寸实体分解法。该方法在ＡｕｔｏＣＡＤ１２．０环境下ＡｕｔｏＬＩＳＰ编程语言已成功实现。

| Abstract: | At the beginning,a brief analysis is made on the entity database structrure and visiting method. With the programming language-AutoLISP with the AutoCAD12.0,the entity name and the joint coordinates of a closed drawing can be easily obtained in a clocckwise or anticlockwise way. A concise,precise,and reliable method,or dimension entity explosion,is proposed to acquire text data of dimension entity on the basis of AutoLISP in AutoCAD. |
