As I am learning SketchUp, I figured to post a W.I.P. I am learning as I work, just having fun with this one. Its pretty much a concept of a fuel depot in the desert where riders can stop, refill and "REFILL." Now this is the future, so autopilot gets rid of the DWI factor haha.
I will make the hovercraft smaller once I am finished modeling it. nothing fully to scale, but the idea is there.
Hey, this looks damn good considering you're still just learning! Good job
If you want it to be even more badass when you're done, I suggest you render it, that way it'll look more realistic with cool lighting and all! Kerkythea is a good one and for free! But maybe you'll want to grasp SU better before you go into the depths of rendering.
