3D technologies are more and stronger included into our life. We are surrounded by the most various technique which we make or we use — cars, engines, computers, printers, TV sets, etc. These are difficult aggregates. Even, in the presence of vocational education, not directly you will also understand – with "what" to suit a side. And if the description in foreign language – the task of mastering of technique considerably becomes complicated. But the created technologies of three-dimensional visualization considerably simplify process of a study of a structure and the principles of operation of the difficult equipment for users. Conditionally the procedure of acquaintance and a study of the principles of operation and a structure of nodes and aggregates can be broken into two directions:

• • studying of a structure and relative positioning of details;
  • visualization of the principle of work.

The section of our website can be an example of the first direction «CATALOGUE of COMPONENTS». He demonstrates as by means of our technologies the list of details (knots) of which an object consists is described. The second direction is presented in the section«STEP-BY-STEP PROCEDURES» . In him, on the example of a toy it is shown how, by means of our technologies, process of visualization of assembly of a product is implemented. During visualization, for descriptive reasons, the product can be rotated in all directions, to consider it under a different point of view, bringing closer and deleting. Thus, process becomes more evident and convenient for understanding. Our technologies can be used not only for creation of catalogs of details of mechanisms and products and visualization of process of their assembly dismantling. They are applied to the presentation of technological processes, by creations of educational stands and complexes, creations of the guides to service of the equipment and other documentation.
