About cesium GIS assets rendering at Autodesk ForgeViewer

Good morning. This is my first topic here, so maybe I’d tell some incorrect things. Thanks in advance.

We are raising a BIM-based platform, using the Autodesk-Forge ecosystem, but we also want to allow users to take advantage of GIS at the same place. We are just starting on researching about how the 3d Tiles and cesium viewer works. Our desire is to be able to mix .rvt and other formats as .nwd with the cesium GIS solution. Is this possible? And then, how could We reach to our goals?
