摘要
讨论了利用智能化尺寸驱动技术实现二维参数化绘图中的问题。首先讨论了几何约束、结构约束与约束判定的关系,基于此关系,利用图形尺寸参数和结构参数实现图形的尺寸驱动,进而利用智能化尺寸驱动法实现参数化绘图。以AutoCAD为平台,通过高级语言C与AutoLISP语言编程,在开发的圆柱齿轮减速器壳体自动化设计系统软件之参数化绘图中得以实现。
In this paper,the problems of intelligent dimension-driven in 2-D parametric plotting are discussed.First,the relations among dimension-constraints,construction-constraints and constraint judgment are discussed.Based on the relations,intelligent dimension-driven is achieved with dimension-constraints and construction-constraints,then parametric plotting is achieved by intelligent dimension-driven.Under the environment of AutoCAD,by editing program with advanced language C and AutoLISP,these key technic are accomplished in the software of auto-designing series of welding cylinder gear retarder.
