3D Scene menu in the Manager UI
The link to 3D Scene is not actively used directly, but takes input from controls in the Product view. It is used during development to "stage/test" your product before you press on the "publish" button on the product page for the product you are going to publish to the planner.
When you want to test your configuration and have generated runtime products, pressing "View Product" button when you have a product selected will open the 3D scene from the Products view
