Here's an example of a project where reality gets thrown out the window in favour of idealistic legibility. The client's concept required a slice of a supercar. The first problem is that supercars have the engine in the back not the front. The second problem is that even if the engine was in the front there would still be a lot of empty space and that wouldn't work for the "pie chart slice" look. So I had to fill this model in with a bunch on nonsensical mechanical parts to get the required wedge look.
This was created in 3D with some photoshop work.
