Initial Versioning Rules
For all Windchill solutions, load files set the initial versioning rules for parts, documents, and CAD documents in the site context. These rules affect the parts, documents, and CAD documents created from within a product or library.
The default versioning scheme used is set when site context rules are established unless you choose to set them in an organization, product, or library context. The out-of-the-box demonstration template named Product Design sets versioning for a product context. For details on the Product Design template, see Out-of-the-box Product and Library Context Templates.

PTC recommends that you establish one versioning scheme for all of your contexts and that you set the versioning scheme in the site context. However, you can override the default versioning scheme for a specific organization, product, or library context.
Documents, CAD documents, and parts that are created from within a project or program context are not versioned objects.
