Abstract: Under the sudden strike of the pandemic, the online teaching of “no class, still learning” rendered the
teaching under outcome-based education (OBE) special. Taking the course “Modern Engineering Graphics” as the
carrier, online teaching that trained students’ graphic literacy and integrated the computer modeling was put forward.
The teaching focused on integrating teaching resources, relying on the network platform, and cultivating the
engineering ability. The teaching process emphasized the student-centered teaching philosophy and strengthened
diversified appraisals. A new mixed system of cartography teaching was constructed, in-class and outside-class, online
and offline, theoretical and practical. It was practiced in the majors of mechanical design and automation. The
following problems were solved, such as poor interaction, difficulties in practice and cartography teaching, and the
lack of actual computer operation in distance learning. Thus, the teaching effect equivalent to the offline course was
attained. It can provide the reformative idea for the teaching of basic engineering courses.
