中文摘要：有时需要批量打印工程图纸，为了节约时间和纸张，需要人们对图纸重新搭配。在分析标准幅面布局要解决的问题的基础上，提出了一种基于积分法的工程图组合排版算法。采用最小图幅为单位分割A0，得到图形拼接可能插入点。所提算法完全以正向规划方法解决问题，不用链表、不用复杂的优化算法。算法实现简单、稳定可靠。该算法已在所开发的叶片锻造模具CAD系统使用中得到证明。
英文摘要：In some case, a batch of drawing sheets is needed printing at one time. For saving the time and paper, the sheets need to reposition manually. Based on analysing the standard sheet sizes, a new automatic layout algorithm was presented, that is digital integration analyzer algorithm. The problem was resolved with forwards planning and without the complex optimizing method. The algorithm is simple, reliable and efficient. It has been proved in a special CAD for forging mould design of turbine blade.
