Too complex? I don't think so. It looks like a box, with another box, with another box and.. You get the idea. It's just like how I model my sceneries. Boxes everywhere, with modifications. The boxes vary in size, width, height, lenght - but it's still a box. If you look at an airport, you should be able to break it down into simple geometric shapes. Box, ball, cylinder. These are the three shapes I mainly break down a building with. Combination of these shapes may create new shapes never before seen, thus giving the idea of "this is an advanced structure". I'll see if I can get some time to show a practical example of what I mean, with the tower at Alicante. The supporting tower is basically three circles with a box or two to stitch them together, and then extruded to give it height. And then there's a hexagon for the tower itself.. OK.. I MADE some time.. [vimeo]13908306[/vimeo] Thanks Ola, finally watched this, looks like good software. I can see your hangars in the background of the duchess, they look great.
