You can control which design view page will display by default. Normally, the page that displays by default is the first page that the user viewed in the contained model, and this might not be the page that actually is displayed when the model is run. Complete this task to control which page the user sees in the design view for contained models.
- Navigate to the page in the container model you want to be the default.
- Click Model -> Cache page for Model Container
The selected page will now display by default when the model runs.
