With development of information technology and beginning of the "Internet plus" era, there arise disadvantages to traditional teaching of 3D software drawing course, which can no longer fit current digital teaching strategy. Based on study of Changchun Sci-Tech University's blended learning modes of four courses: 3D Max software, Rhino 3D modeling software, SketchUp software and Maya image technology, AHP(Analytic Hierarchy Process) is used to develop an evaluation index system for them, and the fuzzy comprehensive evaluation model is used to calculate the score of their teaching qualities. Based on the calculation results, solutions and ideas are proposed for better improving quality teaching resources and promoting students' autonomous learning ability, which could serve as an effective reference and basis for teaching quality evaluations of other related courses.
