If needed: Invite someone to join the model. When the new user joins the model, the Available updates list opens.
The user can then select a baseline or an update to join. The Available updates list shows all the baselines and the updates after the latest baseline. You can select any baseline or update to join, not only the latest. By joining an earlier baseline or update you can go back in the model history, and, for example, check the model state on a certain date.
Joining a baseline is beneficial for users who join the model when there already are many changes made. Joining a baseline instead of an update is also faster.
After joining a model, only incremental update packets are read in from the sharing service.
