Micro-Modeling techniques are readily used to make scaled down model of complex engineering products like electric motor, transformer etc. These Engineering Models resolves pressing issues of engineering products and systems that are critical for their presentation and selling. Size of engineering products is often a big hindrance in exhibition, work-study and training of the product. These models overpower the visualization limits imposed by a large product, e.g. a military tank or a megawatt range of power transformer, by reducing them over a large scale e.g. 1:200. During interaction with customers, product promotion is usually done through brochures, engineering drawings or product description and the only way a customer could see such products is after they have been built over several months and are already paid for; or visits another customer, who has bought a similar product. But these engineering models can come handy in a situation where a customer wants to have the physical feel of the product before giving an order.
