i explained that reverse engineering starts with disassembly and inspection of the component to understand its function and material. Then, dimensional data is captured using tools like vernier calipers, micrometers, or a 3D scanner. This data is used to create an accurate CAD model in SolidWorks or CATIA, applying appropriate GD&T. Next, I verify the design through simulation in ANSYS to check strength and performance. Finally, I prepare detailed engineering drawings and a bill of materials, and, if required, suggest improvements using DFM/DFA principles.
