Apabila Rekabentuk berbantu Komputer (CAD) has become more popular, kejuruteraan balikan telah menjadi satu keadah tunggal untuk menghasilkan model maya 3 matra (3D) part fizikal yang ada melalui pengabungan perisian CAD, CAM, CAE and pekakasan seperti mesin pengukur koordiant (CMM). Kejuruteraan Balikan melibatkan proses seperti mengukur objek, kemudian membenanya semula ke bentuk model maya 3 matra. Obje fizikal boleh diukur dengan pengimbas 3 matra yang menggunakan teknologi CMM, pengimbas laser, pendigit cahaya terstruktur atau tomographi berkomputer .

Kejuruteraan balikan selalu digunakan oleh pihak tentera untuk membolehkan mereka menyalin technologi, pekakasan atau maklumat negara lain, atau part yang telah dijumpai oleh askar biasa di medan perang atau oleh operasi pengintipan. Ia kerap digubakan semasa perang dunia kedua dan parang dingin. Contoh yang terkenal dari WWII diberikan sebagaimana berikut:
Reverse engineering is often used by military in order to copy other nations' technology, devices or information, or parts of which, have been obtained by regular troops in the fields or by intelligence operations. It was often used during the Second World War and the Cold War. Well-known examples from WWII include:
 
Tin Jerry : Askar British dan Amerika sedar yang pihak German mempunyai tin petrol dengan rekabentuk yang sempurna. mereka telah membalikkan kejuruteraan contoh tin berkenaan. Tin berkenaan popular dipanggil sebagai ''tin Jerry'' (Jerry cans).
 
Jerry can: British and American forces noticed that the Germans had gasoline cans with an excellent design. They reverse engineered copies of those cans. The cans were popularly known as Jerry cans.
Tupolev Tu-4: A number of American B-29 bombers on missions over Japan were forced to land in the USSR. The Soviets, who did not have a similar strategic bomber, decided to copy the B-29. Within a few years they had developed the Tu-4, a near perfect copy.
V2 Rocket: Technical documents for the V2 and related technologies were captured by the Western Allies at the end of the war. Soviet and captured German engineers had to reproduce technical documents and plans, working from captured hardware, in order to make their clone of the rocket, the R-1, which began the postwar Soviet rocket program that led to the R-7 and the beginning of the space race.
