The article focuses on comparing the merits and demerits of three teaching modes contributed by the introduction of 3D modeling and 2D computer?drafting in universities in view of analyzing characteristics of modern engineering drawing curriculum.Taking the “descriptive geometry and engineering drawing” curriculum in civil?engineering as the carrier, and guided by outcome-based-education (OBE), the article also puts forward implementation principles and scheme of “segmental integration” engineering drawing curriculum based on Revit. Furthermore, projection theorem, manual drawing, 2D computer?drafting and 3D modeling are detailedly integrated to discuss the introduction and the instructional design of the integration of 3D modeling and engineering drawing especially in terms of plane figures, elementary units, intersection of solid surfaces, assemblies and architectural drawings. The overall teaching process emphasizes student-centered in order to develop students’ ability of teamwork and innovation via collaborative learning within the innovative design projects. Taking 110 hours as an example, the article, in detail, introduces the teaching contents and arrangement of engineering drawing curriculum with “segmental integration” applied.
