Double-walled CNT

Dear Lammps users
I have to draw a double-walled CNT for my simulation. Can anyone suggest any software for it?

Thanks in advance

why not just combine two SWCNTs with suitable diameter?

Sir

I want to have an internal spacing of 0.344nm between two ideal armchair CNTS. So, what chiralities should I use? I am not able to find a relation between these two!
