Building Information Modeling (BIM) technology has become an important development trend in the construction industry, but the survey shows that the application of BIM technology in most construction-type enterprises is still in the pilot stage. As a compulsory course for construction majors, the lack of practical experience of students restricts the teaching effect. Introducing BIM technology into the teaching of plain drawing is expected to make up for the traditional teaching deficiencies through three-dimensional modeling technology, improve the learning effect, and cultivate talents who are more in line with the industry needs. This study adopts the questionnaire survey method and experimental research method to investigate the application effect of computer modeling technology in the teaching of level drafting. The questionnaire survey shows that the average score of BIM technology application in the current construction type building enterprises is 74.24, 59.2% of the enterprises are in the pilot application stage, and only 7.9% of the enterprises are in the full-scale popularization and application. Multi-dimensional scale analysis shows that BIM talent training is one of the key factors affecting technology application. Based on this, the study designed a teaching program for plain drawing literacy based on BIM technology, including improving the practical training courses, developing information resources, carrying out skill competitions, constructing an evaluation system and improving the teachers’ strength. The results of the teaching experiment showed that the posttest mean values of learning attitude, problem solving ability and skill mastery of the students in the experimental class were 3.90, 3.90 and 3.93, respectively, which were all significantly higher than those of the pre-test (P<0.01). The experimental class scored 4.25 points higher on the posttest than the control class, and the independent samples t-test showed a significant difference (P=0.018<0.05). The study proves that BIM technology can effectively enhance students' learning interest, problem solving ability, skill mastery and learning achievement in the teaching of plain drawing, which is of great value to the teaching practice of architectural design.
