This example shows how to number a model that consists of multiple phases, each phase having a different detailing and submittal schedule. This enables you to release drawings for a particular phase at any time.

1. Apply a specific numbering series prefix and start number for parts in each phase.

   For example:

   • The beams in phase 1 get the numbering series prefix B and start number 1000.

   • The beams in phase 2 get the numbering series prefix B and start number 2000.

   

   (1) Phase 1: green

   (2) Phase 2: magenta

2. Ensure that the numbering series are not overlapping.

   For example, to avoid numbering overlaps with the beams in phase 2, phase 1 should not contain more than 1000 position numbers.

3. Select the parts you want to number.
   Tip:

   Use selection filters to easily select parts belonging to a certain phase or parts with a specific start number series. You can also use selection filters to ignore specific phases that are already completed or phases that are not ready for numbering.

4. On the Drawings & reports tab, click Numbering settings > Numbering settings to open the Numbering Setup dialog box.
5. Modify the numbering settings, and then click Apply.
6. Select one of the parts you want to number.
7. On the Drawings & reports tab, click Perform numbering > Number series of selected objects.

   All parts belonging to the same numbering series as the selected part are numbered.
