Reverse engineering, also referred to as back engineering, is a method used to analyze an existing physical component in order to understand its structure, dimensions, and functionality, and then recreate it in digital form. The component being studied can vary significantly in size and complexity—from small mechanical or electrical elements to large assemblies used in complex engineering systems. Regardless of scale, the main objective remains consistent: to generate an accurate digital model that can later be used for manufacturing, redesign, technical analysis, or integration into larger systems.
