Dear Hong, As Eugene mentioned, you should be able to build the full virus assembly using PISA.
Another option is to use the multiscale model menu of UCSF Chimera (default setting is "Biological Assembly") to generate the complete virus assembly from PDB BIOMT records. If this is a new structure any you have only ncs records to build the crystal asymmetric unit, you can still use Chimera/multiscale model with option to apply both NCS and crystal symmetry.
