• To redefine features during UDF placement, they must be selected in the Options > Redefine these features table.

• The features are selected for redefinition either because of variable elements in the UDF definition, or because you select them for redefinition.

• Redefinition of the selected features can be triggered by clicking Edit Definition or by using the Preview buttons to go to a feature.

• While redefining a UDF feature, the Placement tab remains displayed, but unavailable.

• After redefining a feature, the feature check box in Redefine these features becomes unchecked.

• After feature redefinition the UDF definition might become invalid. If so, all Placement operations become disabled except for Redefine these features and Undo All on the Options tab.

• You can select Undo All to remove all the redefinition created during UDF placement.
