【摘要】 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,具有如下特征:自由拖动、动态生成、动态测量、轨迹生成。根据当前约束条件来自动生成几何图像,是约束求解领域的核心问题。本文在前人的基础上,提出了处理一般几何约束问题的完备方法—一AGDG方法,适用于平面和空间几何问题的图形自动求解和生成。将AGDG应用于智能动态几何软件设计中,并得到较好结果。更多还原

【Abstract】 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 has many properties,for example:dragging the object freely,dynamic generation,the dynamic measure,and the dynamic generation locus.The main point in the area of constraint solving is Automated Geometry Diagram Generated(AGDG) according the Geometric constraint.This paper present a complete algorithm in the GCS called AGDG used in the 3D and 2D.We devise an intelligent geometric software according to the AGDG.and get the satisfaction effect.更多还原
