Synchronize numbering with the master model
If you need to include numbering information from areas in the model that have been modeled by other users:
Ask all users to save their working models. This updates the master model.
Number the model. Make sure that the Synchronize with master model (save-numbering-save) check box is selected in the Numbering setup dialog box (see Numbering setup in multi-user mode). This updates your working model to the master model, numbers the master model, and then saves the numbered master model for all users to access.
If you create drawings and/or reports after numbering, you need to save the master model again to make them visible to other users.
