【摘要】 主要研究了面向尺寸智能标注的特征识别与提取技术。通过基于体分解的特征识别技术,将特征造型零件分解成基元体(智能图素)的集合,然后通过特征提取获得与尺寸标注相关的几何特征信息,经过必要参数处理得到能够满足尺寸智能标注要求的基元体特征信息。采用这一方法在CAXA实体设计平台上初步实现了特征的自动识别与提取。更多还原

【Abstract】 Feature recognition and extraction is the precondition of intelligent dimension. In this paper, a feature-modeling-based method on feature recognition and extraction for intelligent dimension is presented. By using the technology of cell decomposition, original feature cells are identified and their feature information is extracted. Suitable parameters for intelligent dimension are supplied by this approach. Several functions of this method have been achieved in CAXA.更多还原
