Abstract: The article describes theoretical approaches to the development of visual-spatial abilities in the process of three-dimensional computer modeling. The main skill that a learner needs to develop in the process of analysis of modeling form is considered to be the result of interiorization of external activity, directed to create a shape. The article describes a system for development of tasks and principles and their application in the practice of teaching 3D modeling. The paper also reports the results of using this method in practice.
