In the paper general tendencies of learning graphics in CAD/CAM are described in the aspects of evaluation of performance. The common problems in learning of such systems and tools, in knowledge assessment and in the efficiency and quality of usage of CAD/CAM in graphics are searched. In time when IT tech-nologies and use of automatization is live topic in researches about technology enhanced learning with the aid of intelligent learning systems is necessary to cre-ate such tools for fast and accurate result of learning process. Adaptive learning and knowledge assessment principle analysis and description of intellectual tu-toring system created are given in the research. The ITS created carries out the compilation of the user’s accomplished graphical operations in CAM/CAD sys-tem, the analysis of the time spent and data processing. These data help to under-stand for which operations the user has spent the most time as well as in how many steps the designer has accomplished the task.
