Research on Automatic Drawing Generation Technology Based on Teigha
The design of the fire alarm system for rail transit is divided into architectural design,mechanical and electrical design,and detailed design.The detailed design is a deeper level of construction design for the entire project,and its function is to provide a deeper demonstration of the rationality and practicality of the system during the construction phase,guiding the construction unit to quickly,efficiently,and accurately install and connect the mechanical and electrical equipment.The system has the characteristics of multiple detection sites,multiple types of equipment at each detection site,and a large number of monitoring modules.Therefore,a large amount of manpower and time need to be invested in the detailed design stage to complete the drawing and proofreading of the detailed drawings.At present,the detailed drawing of various projects mainly relies on manual drawing.This article proposes a Teiga based automatic drawing generation technology,which inputs the detailed design into an Excel spreadsheet.The program automatically analyzes the configuration of the spreadsheet and generates detailed design drawings.Practice has shown that this technology can effectively improve the accuracy of drawing during the detailed design stage,shorten the drawing cycle,and reserve sufficient time for equipment installation,wiring,and debugging in the later stage.
