hi trey, you can use x-ref objects from the file menu. first inset your deat in their correct possition, then select all of them and x-ref them, a new window will open up so you can create a new scene to store the seats in. check hide geometry in the x-ref dialogog window before returning to max. you can even link the file to low poly seats. anyway i hope this help, look up x-ref in the help menu for more in depth info and help.
bye
