Hi Aminudin,
As already mentioned, more information about the design you are working with and what you are trying acheive would help. In the meantime, one answer might be to make your precast model a shared cell, then when it it arrayed each copy will be an instance of that shared cell (rather than a complete copy of all of its graphics content) so will not increase your file size.
