Therefore , it is necessary to acquire the cad model by conventional engineering or reverse engineering . reverse engineering of physical objects refers to the process of creating engineering design data ( including the cad model ) from existing parts by using many digitized technologies and cad technology 在沒有產(chǎn)品cad模型和沒有設(shè)計(jì)圖紙或者設(shè)計(jì)圖紙不完整的情況下,按照現(xiàn)有產(chǎn)品樣件,利用各種數(shù)字化技術(shù)及cad技術(shù)重構(gòu)其cad模型的過程,被稱為實(shí)物反求工程。
