We are processing the Drone image by Pix4D to prepare a OBJ file, then that output OBJ file we need to open in any External software, but once it is open in any external GIS software or Deswik then the OBJ file does not showing the OBJ as Georeferenced, please advice the command or setting how can we make any OBJ file which will open in any external file with Georeferenced
Hi @srgroupit
Welcome to the Pix4D Community 
.
OBJ files are non-georeferenced. Because of this, PIX4Dmatic and PIX4Dmapper also provide an additional file called offset.xyz with the offset so that the project will appear in the correct location in space.
You can learn more here:
Let me know if this helps and if there is anything else I can do for you.
Cheers,
Daniele
