Managed Street (Beta)
"Managed Street" is a 3DStreet system composed of a "Managed Street JSON" format, JavaScript A-Frame components, and custom user interface elements that allow end-users to create, convert, and add procedural elements on a street path.
Using Managed Street
Users can create streets with the new Managed Street format using the 3DStreet Editor. Press the Add Layer button > Streets and Intersections tab > and scroll down to select a "(Beta) Managed Street..." card or drag-and-drop to a specific location in the viewport. These features are still in heavy development and are subject to change.
