Hi David,

Thank you for your response.

I have been able to make the polymer of cellulose. But I need multiple
chains together.

Could you please suggest how can I replicate the same polymer chain or can
I build the multiple number of polymer chain together?

Is there any specific tutorial or command that I need to follow?

Thank you.

Kind regards,
