图纸空间复位系统在数字化建模过程中的研究与开发

R&D of the Spatial Transformation System of Drawing in Digitalized Modeling

建立矿山数字地质实体模型是生产矿山真三维计算机辅助设计系统开发的基础,而将数字化后的二维矿山图纸转化成空间三维图纸的技术则是地质实体建模的关键。基于AutoCAD平台,利用VC++6.0和Object ARX2007技术,结合纸质图纸数字化、基点定位、图形坐标转换等方法,设计研发了图纸空间复位系统,该系统运行稳定、操作简单,易学易用,其结果经实践验证准确、可靠。能很好的解决平面图纸空间复位问题,为数字地质实体模型的建立提供了保证。

The digital geologic solid modeling serves as the foundation of real 3D CAD system platform and the trans-formation from the digital 2D mining drawing to 3D drawing is the key process for the establishment of geologic solid model. On the basis of Auto CAD platform, this paper tends to develop the drawing spatial transformation system by adopting such techniques as VC＋ ＋ 6.0 and Object ARX2007 as well as methods of the papery drawing digitalization, base point location and graphics coordinates transformation. This system runs smoothly and is easy to learn and operate, with practice - proven accurate and reliable operation results. It can well solve the problem of spatial transformation for planar drawing, guaranteeing the construction of digital geologic solid model.
