Computer Aided Design is a technology based on the use of the computer, it is a graphic software that can assist the mechanical or electrical designer.
TVM uses in mechanical design a three-dimensional CAD to achieve real mechanical models, from the single piece to the whole machine. After creating a three-dimensional drawing, on create two-dimensional tables for the effective realization of mechanical parts.
TVM in electrical design creates two-dimensional circuit diagrams with which then realizes the machine wiring and are also used for customer support for potential failed components. The electrical design is also three-dimensional, since it is possible to study how to place the different components inside the machine, so as to facilitate the realization both mechanically and electrically.
