Abstract: Carrying out machine 3D surveying and mapping practice training can help consolidate parts measuring and drawing skills, improve students’ ability to analyze and design expression, and enhance students’ ability of engineering practice. By introducing reverse engineering measurement technology, the objective of surveying and mapping practice, implementation process and the specific requirements were put forward. The principle of selecting surveying and mapping objects was put forward, measuring tools were selected, and 3D feature modeling and reverse reconstruction method were determined. The team leader’s responsibility system was planned. The comprehensive evaluation strategy of the group evaluation, the group self-assessment and the teacher’s evaluation was established. The detailed scoring criteria for group evaluation and teacher evaluation were formulated. The application of the practice training method shows that it is an effective way to enhance the students’ ability of utilizing modern design techniques and methods as well as their employability.

Key words: machine 3D mapping, reverse engineering, practice teaching method
