DGN线型转换的方法研究及应用

Research and Applicationon DGN Line Shape Conversion Method

MicroStation是一款得到广泛应用的CAD平台软件,DGN格式交换是数据处理的难题之一。从MicroStation平台软件的线型管理、自定义线型的工作机制和MicroStation数据结构出发,通过研究分析,提出了利用FME工具实现以DGN格式为目标的一种线型转换方法,并以南方CASS数据为例,详细介绍了转换过程及效果。该方法的研究及应用为字体、颜色等其他MicroStation'资源'的转换提供了思路,为实现DGN格式数据的无损交换提供了方法。有关线型的'资源'知识以及该研究成果可以为平台软件的使用及二次开发提供帮助。

MicroStation is a widely used CAD platform software.The conversion between GIS data formats is one of the difficult problems in data processing.After analyzing the custom line style management and data structure of the MicroStation platform software,it a method to convert the custom line style to DGN format through the FME software is propsed.Taking the South CASS data as an example,the conversion process and effects are introduced in detail.The research and application of this method provide ideas for the conversion of other MicroStation resources such as fonts and colors,and provide methods for the nondestructive exchange of DGN format data.The Knowledge of how its works can help you better use and development to platform software.
