The server seems to be down right now, but it is possible you could also do this using the sym command in ChimeraX (I'm just not sure whether there are options for helical or only point group symmetry):

Hi Binh,

There may well be a way to do this with ChimeraX, but you can also easily use servalcat for this:

Dear all,

Is there a way in chimeraX that I can use to generate a long fibril, say 20 chains, from a single chain with a twist angle of -1.4 degree and the rise (distance between layers) of 4.75 Angstrom. Some thing like this:

I normally used Coot and manually add a single layer into density. 

Thanks,
