摘要
本文提出并实现了基于尺寸约束离线形成的参数化驱动方法，即通过对尺寸的识别理解，自动形成尺寸对图形的约束及尺寸之间的相互约束，达到尺寸约束的自动组织，从而实现参数化尺寸驱动图形．实验证明该方法具有兼容性好，通用性强，方便用户等优点．
This paper presents a method for parametric drive based on off-line forming dimensional constraints. By recognizing and understanding dimensions in engineering drawings,the internal constraint relations between dimensions and drawings are automatically established, and the dimensional constraints are autoorganized. Thus, the parametric design can be processed by means of dimensional drive. It is indicated by a series of tests that the method is compatible, interchangeable and convenient.
