*You will need to have installed both the Multi OIC Viewer and Web AppBuilder - Developer Edition prior to creating an App
* You will also need to have an Oriented Imagery Catalog available on your ArcGIS Online Content page. For easy creation of Oriented Imagery Catalogs, we offer our OIC-Wizard app.
To create an app using the Multi-OIC Viewer widget in Web AppBuilder, please open Web AppBuilder and select 3D and click on Create New
In the Create a New Web App page, select Default (3D) and click Next
Select Widget
Click on Set the widgets in this controller and then click on the + button
Then select the Multi-OIC Viewer widget
Finally, select an Oriented Imagery Catalog (OIC) previously published in your ArcGIS Online My Contents page and click on Add. You can add as many OICs as you have available on your ArcGIS Online My Contents page.
