This article is concerned with the prospects for the implementation of synchronous technology for knowledge processing and transfer by visual methods in the context of end-to-end engineering project-based training. A formal characterization of information about complex systems based on the visual cognitive metalanguage VI-XML, forming a synchronous project-based educational environment, is proposed. This environment is a set of methods, using visualization metaphors, while the object under study is presented from different points of view and levels of detail (expertise). Visualization metaphors form the mechanisms for processing and transferringknowledge by comparing abstract or real objects to visually perceptible images. Visual modeling languages, in turn, are formed by fi xed sets of metaphors and rules for construction of visual models from them. The proposed approach to the presentation of models underlies the universal visual modeling environment, which provides a single interface for creating and editing visual conceptual, structural-functional, and object models. It provides the ability to encapsulate the levels of visual modeling in a single closed hierarchy, accompanying the stages of system analysis and design. The experience of using a universal visual modeling environment in the frame of practical work and group design has proven itself to be good for the solution of educational problems in the fi eld of knowledge transfer in a visual form that is easily interpreted by students.

The article discusses the main provisions of the concept of using additive technologies for digital prototyping of assembly devices in the production of electronic equipment. Approaches to the system design of devices and their components are formulated. General ideas about devices are generalized and systematized, types of fixtures for assembling electronic equipment are classified. A comparative analysis of the methods of classical and model-oriented (drawing-free) design is carried out. Recommendations on the use of additive technologies in the implementation of ‘trial and error’ design methods, the coordinate calculation method, wave technology, design using layout schemes and virtual assembly are given. The tasks that are solved in the process of designing and manufacturing devices in the production of electronic equipment are determined. Recommendations for modeling, simulation and prototyping of devices for testing designs and validating technological processes in order to reduce the time of technological preparation and production are given.
