I always found PyMOL most useful for this - if you have a PDB file
with symmetry records loaded, this command will generate all symmetry
copies within 20 Angstroms:
symexp s = my_object, my_object, 20
Increase the radius to view more of the lattice.
I believe Coot does something smarter where it only draws molecules in
range (Draw menu->Cell and Symmetry, then click "Symmetry by
molecule"). This is probably better for interactive visualization -
the only drawback is that you can't easily save the symmetry copies to
a file, or make pretty pictures.
