AI Technical Summary

⚠Technical Problem

The existing methods for generating horizontal and vertical profiles of railway lines have few control parameters that users can modify, resulting in a lack of flexibility and requiring extensive manual modifications when map output requirements change.

⚗Method used

By customizing control style files, constructing a control style management dictionary, creating custom objects in AutoCAD, setting the current control style according to design requirements, drawing and decomposing custom entities of line horizontal and vertical profiles, and realizing the classification, definition and management of parameters.

🎯Benefits of technology

Without modifying the basic design data, it achieves universality and scalability across different railway grades and design stages, improves mapping efficiency and quality, and meets special mapping requirements.
