【摘要】 尺寸自动标注是提高绘制工程图样效率的有效途径。在研究三维实体造型与工程图关系的基础上,提出了基于特征的尺寸自动标注方法。通过提取三维零件模型的特征信息,生成定形尺寸和定位尺寸,并自动调整尺寸的分配和布局。在此基础上,实现了UG中零件尺寸自动标注模型。更多还原

【Abstract】 Automatic Dimensioning is an effective approach to improve the efficiency of mechanical engineering drawings. Based on the investigation of 3D modeling and drawing,we create shaping dimensions and location dimensions by extract the feature information from 3D parts, then adjust the attribution and arrangement of dimensions automatically. An automatic dimension model has been realized in UG software.更多还原
