Design changes and version variations during collaborative design of large-scale products

In PDM collaborative design processes, version and version number are crucial concepts. A version refers to a specific state of a drawing, document, or data. A version number is used to distinguish different versions; version numbers are divided into major and minor version numbers. Major version numbers indicate significant design changes or important product versions, while minor version numbers indicate minor changes or fixes. In PDM collaborative design, version numbers are used to track historical data and manage different versions of data. When making design changes (ECs), detailed planning and management of the changes are necessary, using version control to maintain data consistency and integrity. Furthermore, the parent-child hierarchy is also an important concept in collaborative design, helping designers better manage data and design projects.
