How do I specify the lenght of a polymer ?

I use MarvinSketch 5.2.4. 

 

Dear Chemaxon,
I work with PolyEthyleneGlycols (PEG's) and I would like to know how I specify in the structure editor that a unit should be repeated a certain number of times. E.g. if I would like to search a polymer with a lenght between 40 to 60 repeating units.

Best Regards

Dear Simon,

please see our documentation about polymers and their drawing:

I hope, this helps.
