铁路工程图层标准现状与编制研究

Study on the Current Status and Development of Railway Engineering Layer Standard

图层为计算机辅助制图文件中相关图形元素数据的一种分类组织结构,是图形元素的元数据。建立完整的铁路工程图层标准可帮助设计人员有效利用、管理和组织设计信息,为图层级协同设计推进提供基础数据来源,促进铁路工程设计数智化转型发展,提高设计效率。本文分析图层在工程设计行业中的重要作用、图层标准国内外发展现状及铁路工程图层发展现状,详细描述铁路工程图层标准编制的目的及意义,明确标准编制的整体思路及编制原则,并阐述图层标准在图层级协同设计、图纸拆分、图形元素管理等场景的应用。

Layer is a kind of organization structure used for classification of related graphic element data in computer aided drawing file,and it is the metadata of graphic element.Establishing a complete set of railway engineering layer standards can help designers effectively use,organize and manage design information to provide basic data source for graph-level collaborative design and promote the development of railway engineering design digital intelligent transformation and improve design efficiency.This paper analyzes the important role layers play in the engineering design industry,the development status of layer standard at home and abroad,and the development status of railway engineering layer,presents a detailed description of the purpose and significance of layer standard for railway engineering,make clear the roadmap and principles of standard preparation,and discusses the the application of layer standard in graphic level collaborative design and base image processing and drawing splitting.
