参数化变型设计中工程图调整技术优化研究

Research on the Optimization of Engineering Drawings' Adjusting Technology in Parametric Variant Design

针对工程图调整技术所存在的方法不完善,耗时长,过程繁杂等不足,对其进行了优化。分析了常用视图比例调整方法的优缺点,完善了其调整过程。研究了模型边线的伸缩规律,提出了尺寸直角的概念,并通过绘制基于尺寸直角的装配布局草图,简化了视图位置调整过程。提出了标注约束元的概念,论述了其对尺寸、注释位置变化的影响,并通过采用基于标注约束元的标注方法,简化了尺寸、注释调整过程。

Aiming at the existing deficiency of engineering drawings’ adjusting technology,such as the imperfectness of methods,the long consumption of time,the complexity of process,etc,an optimization for them is implemented.The benefits and shortcomings of commonly used view scale adjusting method are analyzed and its adjusting process is optimized.By studying the stretch law of model edges,presenting the concept of dimension angle and drawing the assembly layout sketch based on it,the adjustment of view position is simplified.Through putting forward the concept of annotation binding element,discussing the effect it has on the position of dimensions and annotations,and adopting the marking method based on it,the adjustment of dimensions and annotations is simplified.
