摘要
本文在充分考虑机械零件工程图表达特点的基础上,提出了机械零件实体模型的工程图表达中涉及到的工程图隐线消除、剖切表达和多面体模型的曲面化处理等算法。
This paper proposes three methods for the removal of hidden lines and stepped cross-section as well as accurate B-REP evaluation using polyhedral approximation. These methods are related to the engineering drawing expression for solid model of machine parts.
