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