Geometric information input, modification and representation. 3D-object representation in the two-dimensional space: perspective, invisible lines and surfaces, shadowing, animation. Mechanism
display examples. Interactive graphical systems and standard graphical program using for engineering tasks: 3-dimensionalmachinery and equipment (robots), kinematics and dynamics, finite element analysis for stress analysis, the optimal design of mechanisms. The emphasis on creation of the 3D geometrical models and the documentation formatting and usage.
