Any replacement for flexviewer Building Navigator Widget?
Does anyone know of an equivalent Web Appbuilder widget to the old FlexViewer 'Building Navigator' widget by Penbay Solutions? See https://www.arcgis.com/home/item.html?id=a2a0da1d4cbf40de92636f9056e03926 . It seemed like such a good solution to help users navigate a 3D building through a 2D interface. I am trying to replace our old app that used this Widget, but it is not proving easy. The Widget used data layers based on the Local Government Data Model (Buildings, Floors and Rooms) and manipulated the display as the user navigated the relationships implicit in the model (e.g. a Pick a Building, the Building has Floors, Floors have Rooms, Rooms have attributes). Any creative suggestions to approximate this user experience - some of my users are still very keen on this old app! Any ideas greatly appreciated - it's a battle against deprecation
