I want to load files in RVT format,Do you support it?
AFAIK, there is no THREE.RVTLoader. So you have to write a loader by yourself or you convert your RVT files to a different format like OBJ, STL or glTF.
BTW: RVT represents the Revit file format from Autodesk.
maybe u should convert into json format then show in 3js
