Based on the characteristics of modern engineering drawing curriculum system， taking descriptive geometry and engineering drawing curriculum in civil engineering as the carrier, this paper discusses the entry points for the integration of Revit 3D modeling software and engineering drawing courses in terms of plane figures, elementary units, intersection of solid surfaces, assemblies and architectural drawings. Guided by OBE, the paper also puts forward implementation scheme of segmental integration engineering drawing curriculum. The teaching process emphasizes student-centered in order to develop students’ ability of teamwork and innovation via collaborative learning within the innovative design projects. Taking Chang’an University as an example, the paper introduces in detail the teaching practice of segmented integration engineering drawing course, including teaching content, teaching arrangements, and practical effects.
