Revision schemes define how part revisions are named (for example, alphabetic A, B, C or numeric 1, 2, 3). You can configure multiple schemes and set one as the default.

​
Revision scheme format

A revision scheme’s format defines the sequence of characters a revision can use. You build it from segments and separators:
  • Click A–Z to add an alphabetic segment (A, B, C, and so on).
  • Click 0–9 to add a numeric segment (1, 2, 3, and so on).
  • To place a separator between segments, type a single character in the Separator field and click Add.
A format must include at least one numbering segment (A–Z or 0–9).

​
