Hi I am new in this field and I am interested in designing an airport for AUH. However, I am so new at this I can't seem to figure out where to start. I understand there are many tools for different purposes. Are there any tutorials guides on where to start. Basically, what I want to achieve is to design the buildings of Abu Dhabi International Airport. And I am guessing from this is that I might need to work on the terrain first, build the proper afcad file and then design the airport building structure. If there aren't any tutorials, can someone guide me on how to start and where and what to look for ? Thanks.
