Changes to numbering schemes are made by adding or modifying object initialization rules that define the default number value in the context where you want the change to be in effect. The numbering scheme can be set in the number attribute defined for parts, baselines, documents, CAD documents, dynamic documents, and change objects using the AttrValue tag or the VarDef tag. The numbering scheme can be set up as follows:

You can turn off autonumbering in a specific context by specifying no constraint in the AttrConstraint tag.
