Hi @shashank.baganeACM if you check that last Exception message, it is telling you that both host and link models do not share the same coordinates, try using the OriginToOrigin one instead or fix the shared coordinates among your files before using the SharedCoordinates node:
Note that with your method the file(link) is linked and loaded in your file(host) but it needs an instance of the file(link) within the host file.
