Releasing preliminary structures

Creating precise and imprecise baselines

Depending on the configuration of your structure, you can create the baseline as a precise structure or an imprecise structure. If you want a precise structure of a process, you must also baseline the product structure and plant structure first to be able to reproduce the revision status of the PDI in the future. In this case, all the relevant structures (product, plant and process) must be precise to allow their accurate reproduction in future sessions.
