Mechanical Drawing is a compulsory technical basic course for engineering majors in institutions of higher education. It was accredited as a "Golden Course" by the university in 2019 and a First-Class Course of Liaoning Province in 2020. As a crucial carrier for cultivating students' initial engineering thinking, establishing their professional competence and laying the foundation for their vocational literacy, the course is closely aligned with the requirements of engineering education professional certification, serves the talent training objectives of multiple majors, and occupies an important position in the talent training system of engineering disciplines.

This course is oriented towards new engineering disciplines, based on the new requirements of industrial development, and relying on regional economic construction and the mining characteristics of the school. It always adheres to the educational philosophy of "carrying the way through graphics and cultivating abilities with craftsmanship", centers on students' development, and through inheritance, innovation and integration, builds a new educational system for the Mechanical Drawing course that integrates "refining thinking, enhancing ability and forging the soul" through four paths: system reconstruction, technology empowerment, ideological and political integration, and evaluation innovation. The teaching quality of the Mechanical Drawing course has steadily improved.
