摘　　要：“清华山维EPS”软件中斜坡面符号化出方向线时需要获得该斜坡面转点处的位置信息。传统的方法是把数据导入“清华山维EPS”软件,在软件中逐个找到斜坡面,最后在斜坡面的转点处用“J”键给斜坡面赋转点位置信息。这种方法需要针对每个斜坡面人工指定转点位置,不仅造成重复工作量同时存在人为遗漏问题,大大降低工作效率。为克服这一不足,应用“Microsoft Visual C++”结合“ObjectARX”对“AutoCAD”进行二次开发。在“AutoCAD”软件中实现斜坡面赋值转点位置信息自动化,在“清华山维EPS”软件中编写“Visual Basic Script”脚本用于确定斜坡面转点处节点类型,最终实现斜坡面批量自动符号化功能,大幅提高了工作效率,具有较高的应用价值。When generating the direction line of the slope surface in the“Qinghua Shanwei EPS”software,it is necessary to obtain the position information of the slope surface turning point.The traditional method is to import the data into the“Qinghua Shanwei EPS”software,and then find the slope surface one by one in the software,finally use the“J”key to assign the slope surface turning point at the turning point of the slope surface one by one.This method needs to manually specify the position of the turning point after finding each slope surface,which causes a large amount of repetitive work and also has the problem of artificial omission,which reduces the work efficiency of the project.In order to overcome this shortcoming,this article uses“Microsoft Visual C++”combined with“ObjectARX”to carry out the secondary development of“AutoCAD”.First,realize the automatic assignment of turning point position information for the slope surface in the“AutoCAD”software,and then in the“EPS”software The“VBS”script is written in,used to determine the type of node at the turning point of the slope surface,and finally realize the batch automatic symbolization function of the slope surface,which greatly improves the work efficiency and has higher application value.
