Engineers worldwide use the ISO GPS (Geometrical Production Specification and Verification) as a common language to express and exchange the geometrical information of a product and its digital twin. This paper presents a survey of engineering education of the Geometrical Production Specification and Verification (ISO GPS) in China. The research was conducted in 2021, and the purpose is to better understand the current situation in the delivery and usage of ISO GPS. It consists of a literature review of 66 published textbooks, an online questionnaire from 325 educators/students/engineers, who are from five universities and a standardisation committee. The results of this survey are presented and discussed graphically. The results show that:1) there is a significant gap between the textbook teaching and the latest ISO GPS standards; 2) the frequency of the latest ISO GPS usage is relatively low; 3) the current delivery methods cannot address the requirements of end-users soundly. A discussion of the possible solution is presented as well.
