| 摘 要： | 结合参数化设计的各种方法，建立自适应参数化CAD图块数据库系统。该系统从图形数据库入手，建立组成几何实体基本图元的图素数据库，并根据图元之间的约束关系建立约束库，使得图块的各种信息更加完备；还充分利用AutoCAD软件的开放性，在AutoCAD中建立了一个内嵌的图库扩充和复用菜单，使得图块的复用显得更加灵活、方便、简洁高效。

| Abstract: | Based on all kinds of parametric designing method, an adaptive parametric CAD block database system is put forward. Through learning the structure of graphic database, the system constructs a graphic unit database storing the information of basic graphic unit and a constraint database storing the relations among graphic unit, so the integrated information of the block is stored. Furthermore, as AutoCAD is an opening software, the system constructs a menu object which can not only expand the graphic database but also reconstruct a graph. With the menu management, the system makes the reuse of block more flexible, easy and efficient. |
