Recently my class have been on Sketchup. This is one of my Sketchup designs - a train. Underneath, is my All-in-one car. I've been given many questions, like "Why does your train look like Thomas the Tank Engine?"
The reasons for those questions are: Thomas was the easiest design that came to mind. I felt that an ordinary car wouldn't be enough, so I added and added until I was satisfied. Lets put it this way; I love creating unique things and sharing them. So that's why I made these designs.
