摘要
分析了三维标注的发展及优势,总结了参数化的三种实现方法,介绍了基于参数化过程的自顶向下设计方法。再以平推门为例,在三维设计软件Pro/Engineer上实现了平推门自顶向下的设计过程,建立了平推门的三维模型。依据GB/T24734-2009标准对三维模型进行三维标注,在三维标注尺寸的显示方面,提出了分视图标注、特征的标注尺寸与图层相互关联的管理方法。
article analyzes the development and advantages of 3D annotation summarizing three methods of the parameterization, introducing top-down design method which is based on the parameterizing process. Then taking the example of swing door, top-down design process is realized and a three-dimensional model is established on the 3D design software Pro/Engineer platform. According to GB/T24734-2009 principle 3D annotation is apply to 3D model, multiple views and associating features and layers are puted forward in displaying of 3D dimension.
