The paper is devoted to the improvement of quality in designing of machines on basis of the advanced computer technologies. The scheme of the high technology system of virtual prototyping for machines is considered on the example of the Machine Engineering Computer Center at the SERUE "Belavtotraktorostroenie". The center realizes a development and a settling of modern high technologies in virtual designing, modelling and tests for all kinds of machines. They allow to solve questions from an idea and concepts up to the conclusion about an estimation of running ability and competitiveness of machines.
