Abstract: In order to improve the efficiency of crane drawing for front-line technical personnel in construction enterprises, enhance the quality of lifting and hoisting plans, and avoid potential lifting problems in advance, a general technical route for parametric drawing of crane three views based on Zhongwang CAD software is proposed, covering drawing standards, parameter settings, and drawing process settings. A plug-in tool based on Zhongwang CAD has been developed, and the parametric drawing process of crane three views is introduced using a 100 ton truck crane as an example. The results indicate that the crane three view parametric drawing tool has extremely high practicality, effectively improving the drawing efficiency and quality of relevant technical personnel, and laying a good foundation for the development of new quality productivity in enterprises.
