I need to get room/area objects with the hierarchy of linked objects from the Revit model via Forge. Right now I am using this project as a starting point. Unfortunately, the room information is lost. As far as I understand, it is removed during the translation process. There are some workarounds like this one, but it doesn't seem to work for our case. Is there any straightforward way to retrieve room information from rvt in Forge?

Is there a way to find the Revit version of a file on BIM 360 without downloading the .rvt file? I found a similar question here, and Eason's answer suggests using the Design Automation APIs; however, currently the Design Automation API only supports AutoCAD. I know there's a Design Automation for Revit in beta, but is there any way of getting the Revit version without DA4R?

I've implemented offline viewing based on the tutorial and github here. The problem I'm having is forge is looking for the db jsons in an odd location that makes url pathing awkward. The files in particular are 'objects_attrs.json.gz', 'objects_vals.json.gz', 'objects_offs.json.gz', 'objects_ids.json.gz', 'objects_avs.json.gz'. For some reason the forge viewer strips two layers of directories off the url then looks for the files there. Afterword Forge looks for the files in the original location but, looks for the straight json instead of the gziped jsons.

This can be handled in a few hacky ways like creating two arbitrary parent directories in the url and accepting files at the higher url as well. Or unzipping the gzips and saving them in location. But, these kind of hacks could easily be unstable if I'm not exactly right about the forge implementation.

Is there any reason these files are searched for in a different location? For example are these files also used by the 2d files not just the 3d files? Are there other files like this?

We recently came across these slides: https://www.slideshare.net/CyrilleFauvel/introducing-the-forge-arvr-toolkit

And slide number 20 made us VERY enthusiastic!

Is there actually a Forge to Unreal Engine 4 pipeline? We're aware of the Unity and 3ds Max pipelines, but any information related to the UE4 pipeline would be highly appreciated.
