Over the past couple of years, I've built a Boeing 727-100 ( http://www.mikejamesmedia.com/b727_100_01.html ) and a Boeing 787-8 in 3D. ( http://www.mikejamesmedia.com/b787_8_01.html )
Now I'm working on Boeing's new 747-8 "Intercontinental", and if you like to follow along with these build articles, you'll find this one at http://www.mikejamesmedia.com/b747_8_01.html
Here are a couple of renders of the model as it stands today.
