Hello,
Currently bringing in data from other resources into Revit create heavy models which really effects the operability of the Revit models, these 3d models coming from various different sources can be converted into .GLB easily and are really light in size and can be reduced majorly, so if Autodesk can program .glb importing into Revit through Insert options it will be really helping a lot of MFG. Engineering folks to integrate their models into Revit.
