Editing Family Table Attributes in Windchill
 |
Activity with family table objects is only available in Windchill PDMLink or Windchill ProjectLink.
|
The attributes of generic or instance Creo Parametric family table members can be added, removed, or modified using the Edit Attributes page. However, due to their interdependency, additional members of the family table may need to be checked out in addition to any whose attributes you want to modify.
This topic reviews the classification of family table attributes and describes the requirements for, and results of, attribute modification.

|
Creo Parametric parameters are analogous to Windchill attributes. When mapped to each other, their values are propagated from one application to the other.

Classification of Family Table Attributes
There are three classifications of attributes for Family Table objects, as described in the following table.
|
Attribute Class
|
Description
|
|---|---|
|
Generic-driven
|
An attribute (parameter) that has been designated in the generic model, but not added as a column to the Family Table. All instances reflect the same value as the generic for this attribute.
|
|
Inherited Table-driven
|
An attribute (parameter) that has been designated in the generic and has been added as a column to the family table, without assigning a unique value to the instance. The Family Table editor in displays an asterisk (*) for the value for the instances. In Windchill, the value displayed for the instance is the same as is displayed for the generic
|
|
Independent Table-driven
|
An attribute (parameter) that has been designated in the generic, has been added as a column to the Family Table, and a unique value has been given to the attribute either via the family table editor or the Windchill Edit Attributes page.
|
Modifying Generic-driven Attributes
When adding, deleting, or modifying the value of generic-driven attributes, all family table members must be checked-out. If your initial selection of objects did not include all members, upon clicking OK on the Edit Attributes page, the Confirm window appears, listing the additional instances that need to be checked out. Clicking OK checks out the additional instances to allow the Family Table to be modified. Clicking Cancel returns you to the Edit Attributes page without modifying the Family Table.
Modifying Inherited Table-driven Attributes
When you modify an inherited table-driven attribute at the instance level, it becomes independent. That is, its value is no longer driven by the value of the generic. Therefore, only an instance whose value is being modified requires a checkout.
Modifying Independent Table-driven Attributes
Modifying an independent table-driven attribute requires only that the instance whose value is being modified is checked-out.
