This video explains why managing SOLIDWORKS data in a centralised system is essential. Storing files on local drives or shared folders often leads to duplicates, confusion, and version control issues. A Product Data Management (PDM) tool like SOLIDWORKS PDM or the 3DEXPERIENCE platform ensures secure storage, controlled access, revision tracking, and easy retrieval of parts, assemblies, drawings, and related documents. PDM systems also support remote access, markup, and collaboration. SOLIDWORKS PDM offers high configurability and perpetual licences, while 3DEXPERIENCE provides a cloud-based, scalable solution with minimal IT overhead and subscription flexibility.
