It is generally said in the automobile industry that UG is widely used, but many companies use pro/e and catia. As far as I know, FAW mainly uses pro/e, SAIC mainly uses UG, Chery mainly uses UG, and Southeast Auto mainly uses catia. Of course, this is not absolute. In fact, most companies mainly use one kind of software, such as pro/e used by FAW, but we used UG in Wuhan FAW, such as Southeast Auto. ! !
