This standard alphabetic scheme is defined in wt.properties using the following default property settings:

When a new view version of a part is created, by default the versioning scheme begins again in the new view.For example, a new view version of version B (Design) is assigned the identifier A (Manufacturing). If versions of the part already exist in the new view, the new view version continues the versioning scheme. For example, if version B (Design) exists and version A (Manufacturing) exists and a new view version of B (Design) is created, the new version is assigned the identifier B (Manufacturing).

For a new revision of a part, document, or CAD document, the identifier is incremented according to the simple alphabetic versioning scheme. For example, a new revision of version B (Design) is assigned the identifier C (Design).

As described in the previous section, the use of the simple alphabetic versioning scheme is defined by specifying wt.series.MulticharacterSeries in the wt.series.HarvardSeries.level.<level number> properties. For example:

The out-of-the-box Harvard series that is defined in wt.properties is named wt.series.HarvardSeries and uses the property settings described in this section. The wt.series.HarvardSeries series is used as the default versioning series in the object initialization rules loaded.
