Measurement units overview

Classification classes can contain only metric ICOs, only nonmetric ICOs, or both. If your Classification administrator specifies that a class can contain both, you can search for an object using either of the unit systems you define, and the search mechanism finds a match, regardless of the unit in which the object is stored. For example, if you search for a bolt with a width of 5/8th inches, the classification search mechanism finds a bolt that is stored with a width of 1.6 centimeters.

Teamcenter displays the unit of an attribute value as a hyperlink beside the value. You can change this unit for viewing or searching purposes. If a unit is not hyperlinked, Teamcenter cannot find the unit in the Unit Definition class. If the attribute is not yet used in any classes, the classification administrator can change the unit in the attribute dictionary or add the new unit definition to the Unit Definition class.

The unit in which you save an ICO is referred to as the storage unit. Teamcenter displays the storage unit in bold type in the list of available units.

When working with legacy data, Classification searches for the object ID of the unit or, if it does not find that, the display name. If it finds a match, then it displays the hyperlinked unit label. If Teamcenter does not find a match, it displays the legacy unit label that you cannot change.

Tip

Type the unit in the attribute value box along with the value. Teamcenter changes the unit for you automatically.

If your administrator enables optimization for attribute values, these are displayed using the most readable unit with the least number of leading or trailing zeros.
