Cross section of tower foundation is of great significance in transmission line engineering.At present

the drawing methods of cross section of tower foundation are mostly based on the secondary development of AutoCAD

which exists certain inconvenience in environment configuration and operation.Based on Python developed a new type of drawing tool for cross section of tower foundation

which optimizes the requirements of data processing

environment configuration and parameter setting

it realizes the integration of data reading

data processing and tower base section drawing to get the automatic drawing tool.The practical application of±800 kV UHV DC transmission line which links LongDong to ShanDong shows that the tool for cross section of tower foundation proposed has improved the efficiency and quality of mapping.
