基于拓展LIMD算法的智能动态几何软件设计

The Design of Intelligent Dynamic Geometric Software Based on the Enhanced LIMD Arithmetic

几何约束求解技术是新一代智能化参数化CAD的核心技术之一,是CAD领域的一个前沿课题.其目的是提供工程图形的自动求解,其主要特点是:自由拖动元素、动态图形生成、动态测量、动态轨迹生成.LIMD是约束求解中一个应用较广的算法,作者对该算法进行了拓宽和改进,提出了具体解决方法,并得到了较好结果.

Geometric constraint solving（GCS） is one of the key techniques of the current work of developing a new generation of intelligent and parametric CAD systems. It is used to give designers a way to generate the engineering drawings automatically. It has many properties, for exampie： Dragging the object freely, dynamic generation, the dynamic measure, and the dynamic locus generation. Locus Intersection Method of dimension d（LIMD） is a typical algorithm used in the area in GCS, This paper extended this algorithm and have the widen range to solve problem, and get the satisfaction effect.
