CESIUM 3D Objects import to online viewer. -- 2

hi folks, Looking for help in one of the Steps on my project with Cesium online viewer and personal library for clients. Have managed to import non-edited Mesh .3mx files and view them but there is also a possibility to combine different type of 3D format files into one project and view them in one piece (point is to visualize 3D mesh with additional objects e.g. .OBJ.). One of the big questions is Positioning and Coordinate systems as I do not have a clue how to use .js in this but do have some basics on what we need to visualize and precisely, where. Manufacturer's site: [login to view URL] Shortly, I need to find a person who could help out figuring out methodical part for managing such a 3D online viewable library with combined non-edited 3D mesh exported from Bentley Context Capture (example download directory: [login to view URL]) and additional 3D objects on it (roads, buildings etc. etc.) Example of what I need: [login to view URL] As you clearly see, its a cut out space switched with .OBJ or etc. objects.
