The paper focuses on the application of new e-learning materials at the University of West Bohemia in Pilsen at the Faculty of Mechanical Engineering in the Department of Machine Design. These study materials are based on an injection mould which has been previously applied in practice. This is the main advantage of E-learning materials. They help students to become familiar with and master design issues from a practical viewpoint. The e-learning material is written in a structured and unified form in the following sequence: basic information about the injection mould is given in the Introduction, and in the second part the student can view active two-colour 3D models coloured according to function and machining technology. E-learning materials include drawing documentation of the main assembly and subassemblies. They consist of manufactured
