dump the lattice

Dear Lammps users,
I am working to make an alumina lattice by lattice custom command. how can I dump this command to be insure regarding my model?!

I do not want to make a simulation at this time. Ijust want to check my model structure by visulization with dump.

You can use the write_dump command: http://lammps.sandia.gov/doc/write_dump.html
