基于ObjectARX 2007的地质断面自动填充方法

THE AUTOMATIC FILLING METHODS FOR STRATIGRAPHIC SECTION BASED ON ObjectARX 2007

公路铁路选线CAD软件中,断面的分层地质符号填充是必不可少的。在研究AutoCAD图形数据库的结构的基础上,基于AutoCAD 2007绘图平台,运用Visual C++2005编译环境,结合ObjectARX库函数,对图案填充对象的创建原理、图案符号库的建立、填充区域边界数据的构造方法等方面进行了探讨,实现了线路纵断面的分层封闭区域的自动生成和地质符号的自动填充,极大提高了设计效率。

In the CAD software for highway and railway route selection design,it is absolutely necessary that the lamination pattern be filled in the route stratigraphic section.On the basis of studying the structure of AutoCAD drawing database,and on the drawing platform of AutoCAD 2007,the authors made a tentative discussion on the generation of filling boundaries,development of hatch pattern library and invoking of pattern,using Visual C＋＋2005 compiling environment combined with library functions of ObjectARX.With these methods,we can accomplish automatic generation of closed field boundary and calling-filling of the hatch pattern.
