what i would suggest is highlight ALL of the things you want in your intro then copy and paste, using any gridlines as references and then checking everythnig is aligned right and select it all and move it inwhichever direction you need to......i did this with a base i made and quite quickly managed to do it,
optionally you could email me the mission, and mods (speratly) if needed and ill do it and snd the mission back to you........just a question hat version of ofp have you got, if its resitance i wont be able to do it straight away but in a day or two i might get it
check out my mission in the MISC section of ATWAR called Everon helo support base and maybe give me your opinion and/ or learn from it
