Hello,
I am trying to export the top faces of a surface mesh file (obj) format.
for this I am
1. opening the object in paraview
2. using the selection tool to select the desired faces
3. extract selection
4. extract surface
5. save data…-\> save obj file
but if I open the obj file I think it is corrupted or something. in blender it is empty, and in paraview it crashes paraview without any error
I am doing something wrong? or is this a bug?
here is the obj file [FileSender](https://filesender.renater.fr/?s=download&token=6f63306d-f6f1-49f9-9aec-7f44062d5b9e)

the issue was due to the array of point data, when removing all of them the exported file was okey
