The object of Construction Drawing course is the freshman in the teaching process, who don' t understand the construction. The traditional teaching methods can' t not only cultivate students with sufficient spatial ability, but also adapt to the modern construction industry. BIM technology not only has a very high visual quality, but alsohas a strong information transfer function. The application of BIM is used to the practice of civil engineering drawing for building perfect information model. According to the professional requirements, through the three-dimensional translation, rotation, zoom, roaming and other functions, viewingdifferent viewpoint of the building is by switching models of buildingsto enhance the ability of space imagination of students and cultivate students'perceptual knowledge of the building structure. Students understand components of buildings by building a building model on themselves. The development of teaching reform and construction are promoted by participating in BIM contests in information age. At the same time, it provides practical basis for our colleges becoming applied technical college.
