Creating Target Models

Source (parent) models can have multiple target (child)models under them. Contents in target models can be independent of the source model or replicate the objects and properties of their source model. Using the Auto Sync feature, you can sync any changes introduced to the source model with its target models.

To create target models, follow these steps:

  1. Right-click a source model and click New Model.

    2. The Target Model window appears.

  2. Enter appropriate values in the fields. Refer to the following table for field descriptions.
    3. Field Description
    Name Specifies a name for the model
    File Name Specifies a name for the model file. This field is auto-populated.

  3. Click OK.
