^^ true. Although its not the best way to add buildings in my opinion.
The problem is when you come to add more buildings, for instance another hospital. But wait you have already added one, you have to clear your instance building table and readd.
I add buildings by creating an SQF file for each group of buildings or each particular project. Then executing it through the init.swf file in the pbo. Yes it makes the mission PBO slightly larger but it takes load off the DB and its a shit ton easier, as the editor makes the file for you, all you have to do is edit it slightly and pack it in the pbo. Also if someone then notices a bug in one of the buildings, you can comment out the SQF file your having problems with, repack and restart and boom, the issue is gone until you have time to fix it. Rather than trawling through the DB.
Anyways, all that is just my opinion and a full guide of how I do it will be posted tonight, If I get off my arse
