Inspection information in intelligent coordinate measurement contains tolerance information and geometric information，and the recognization and extraction of the information is the key factor for the integration of computer aided design and coordinate measuring machine. This paper introduces the fundamental principle of intelligent coordinate measurement，and reviews the development of extracting inspection information research work. Based on the current development status of full 3D digital design technology，a model based definition method of recognizing and extracting the inspection information is proposed. Considering our current research subject and the part model built in general 3D design software，the process and result of information recognization and extraction are presented.
