Dude, this question is not difficult to answer at all. I recommend you to go to Jiangsu SOLIDWORKS to represent Suzhou Zhuosheng Information Website. The so-called SOLIDWORKS PDM is actually data management. Simply put, when you build more models with SolidWorks, the problems of version, data storage, permissions and so on will become a headache. If it is not handled well, it will not only improve the design efficiency, but also waste time because of too many slow searches. Or the design is invalid because the document version update is not notified to the peers in time. It is more likely that the permissions are not set well, which leads to a large number of employees copying the company's core design model. The above problems belong to the management category of PDM. If you have any further questions, please ask them Please give points. Thank you.
