【摘要】 由于尺寸的交互式标注存在效率低、易出现漏标和重复标注等缺陷 ,CAD系统中尺寸及公差的自动标注技术越来越受到重视。目前 ,此项研究仍未成熟。现就尺寸及公差的无干涉自动标注问题提出了对零件及尺寸标注类型等进行统一分类编码、在视图内分区域标注等几点策略。更多还原

【Abstract】 Due to the limitation of the automatic dimensioning in CAD system, such as low efficiency,the missing and the repetition of dimensioning etc, the automatic dimensioning becomes more and more attended. At present, it is still imperfect. As to the strategy of automatic dimensioning in CAD, in this paper, the authors put forward several ideas to solve the interference of the dimensions and tolerances.更多还原
