## ImportReferencedDelta

### Introduced

v6.0

### Description

Imports a referenced model delta object from a specific file. The file must be in a delta format previously exported using the ExportDelta command or it can be an external storage file from an existing model delta.
A Delta is basically a 'diff' or list of modifications made to the components of a reference model. You can specify which modifications should be tracked in each delta (eg., track only expressions and constraints vs. tracking all animation, etc.). Each model can only have one delta associated to it and each delta contains the name of the model to which it is associated. When importing a delta while there is already a model delta for the model, the user is prompted to chose whether to use the new delta instead of the old one, or just to load the model delta with no target.

### Scripting Syntax

    oReturn = ImportReferencedDelta( FileName, Model, [Reference], [Interactive] );

### Return Value

The imported Delta

### Parameters

Parameter | Type | Description
--- | --- | ---
