Abstract: Drawing technology is an important branch of engineering graphics, and its task is to improve the internal and external quality of products based on advanced drawing technology. The reformation and development of drawing tools and drawing methods are studied. The shortcomings of commonly used drawing tools, such as drawing board, T-square, triangle ruler and protractor etc., are analyzed and corresponding reform schemes from materials, safety, ergonomics and other aspects are proposed. This reform is positive not only for its practicability but also for its environment-friendly and sustainable development.

Key words: engineering graphics, drafting techniques, drawing tools, tool reformation
