Thank you so much for the info. I am looking to do small GA airports and this is the kind of info I have been looking for. It is quiet a complex process, but I want to create airports with the same quality as your Regina, so I guess I have some learning to do. :)
I have decided I am going to try to build an airport for fs9, well this is my third try to learn this skill. What tools do you use and what is your workflow like? I really want my airports to look like yours.
