【摘要】 二维图样的多视图生成及联动问题是CAD领域中的一个难题。在对工程图样的投影关系进行深入分析的基础上，提出投影式多视图图样的智能生成方法，探讨视图间的投影规律，并对图样中的形体自动消隐问题和视图信息的转存问题等提出切实可行的技术路线。该方法已用于大量的二维工程图样，取得了良好的效果。更多还原

【Abstract】 Generation of 2D mutli-views is one of the difficult problems in CAD fields today. On the basis of deep analysis to projection relation in engineering graphics, this paper puts forward a automatic generation algorithm by projection for 2D multi-views, Here, we discuss about the projection principles, and give some practical methods to solve the problems of auto hiding and saving the messages of the views. This algorithm has been used to treat a lot of 2D engineering graphics successfully.更多还原
