根据采矿CAD图形的特点,提出了一种构造式几何约束系统,并使用有向约束图表示约束模型,在交互绘图的同时直接建立参数化图形的约束模型.此方法在建模过程中避免了过约束和欠约束的出现,在求解的过程,将计算量从整体下降至局部,同时通过添加方位约束解决根的选择问题.

This paper presents a structural geometric constraint system, expresses the constraint model with the directed constraint graphics, and builds the constraint model of parametric graphics during drawing the graphic object in the process of modeling.This method can avoid under-constraine and over-constraine in modeling process and ensure the well-constrainted model at any stage, while in the solving process, this method can reduce the searching and solving from the whole to the local, and solve the root identification problem with the aid of location constraints.
