Imported feature revisioning

When you import weld, datum, and arc weld features using the me_import_mfgs utility, Teamcenter compares information in the PLM XML file to what is already in the product structure and:

• Updates only the features that have changed.

• Adds new features that are not present in the structure.

Note

To update a feature, at least one major property must be changed for that feature.

The following properties are used as keys for comparison.

• Occurrence (occurrence name, relative transformation matrix, connected to relation)

• Revision attributes (revision name)

• Form attributes:

Weld points	Datums	Arc welds
Resistance	Type	Depth
Weld_class	Major control coordinate	Method
Weld_designation	Position (x_pos, y_pos, z_pos)	Process
Weld_type		Weld_type
Weld_force		Weld_length
Weld_time		Weld_volume

This diagram illustrates how feature revisions are handled. If the feature has a working status, then the existing revision gets updated but not revised, and is renamed. If the feature has a release status, a new revision is applied.

Note

If the weld, arc weld, and datum manufacturing feature containers—the parents of welds you want to add, remove, or update in your BOM view revision (BVR)—are not writeable, the import will automatically revise those containers.
