A profession which deals with construction, designs, manufacturing, and maintenance of different kinds of products, structures and systems. There are two types of engineering at a higher level – Forward Engineering and Reverse Engineering.

Forward Engineering: Forward Engineering is the conventional procedure of moving from high-level reflections and legitimate designs to the physical execution of a framework. In a few circumstances, there might be a physical part with no technical information, for example, illustrations, bills-of-material, or without engineering data, for example, thermal and electrical properties.

Reverse Engineering: The way toward duplicating an existing segment, subassembly, or item, without the guide of illustrations, documentation, or a display of the plan is known as Reverse Engineering.

Reverse Engineering can be seen as the way toward analyzing a framework to:

•    Distinguish the parts of the structure and their interrelationships.

•    Make illustrations of the system in another shape or higher amount of deliberation.

•    Make the physical portrayal of that system.

In various diverse fields like software engineering, consumer products, microchips, electronics, mechanical designs, automotive and entertainment, Reverse Engineering is commonly used. Just in case, when a new product launches in the market, various other similar manufacturers or competitors may buy the product and disassemble it to find out how it was made or what products have been used or how the other had made it. To defeat a patent on another company’s manufacturing process, many chemical companies may use the process of Reverse Engineering. In the case of civil engineering, many leading companies follow the building and bridge designs to prevent any chance of catastrophic failure. Any good source code is a variable for another good source code in case of software engineering.

In different cases, designers provide an illustration of their plans by using plaster, clay, wood or rubber, but a CAD model is necessary for manufacturing the part of a device. Designing with CAD may be difficult or challenging because, with the flow of time, products become organic in shape. The CAD model may not look or appear similar to the sculpted model. As the physical or sculpted model is an information source for the CAD model, this above malfunction can be solved with the help of Reverse Engineering. This process is also called apart to the CAD process.

To compress product development time in manufacturing, Reverse engineering is another reason for getting the job done. Various developers and manufacturers are constantly trying to find a less time-consuming method to market a new product in this intensely competitive global market. Manufacturers and developers are being assisted by Rapid Product Development for modern technologies and innovations to achieve the goal to reduce product development time. With the use of Reverse Engineering, the digital form of a 3D product or model can be easily captured, then by allowing some remodeling, the product can be sent for rapid manufacturing.

Reverse Engineering helps in duplicating an existing part by collecting information about material properties, physical dimensions, and physical features. The cost/profit analysis and a product analysis must be conducted to maintain the reverse engineering projects before attempting reverse engineering.
