Chimera has lots of different ways for building multimers using crystallographic symmetry information. If the symmetry information is already in the file, it is quite easy. Otherwise, you would have to specify the symmetry yourself in a command.
“sym” command (which also allows you to enter the symmetry yourself if needed)
… and two graphical interfaces,
Unit Cell tool
Multiscale Models tool
I would probably try “sym” first just to see what happens, i.e. if your dimer is open as model #0 and you think the input file has the symmetry information in it already as BIOMT matrices, try:
I hope this helps,

P.S. you can also fetch predicted biounit from PDB, see menu: File… Fetch by ID
