Can't Zoom out enough?

So I've had the game a long time now and I still love it, eagerly await the next update
But I feel like when I create a finished engine, no matter the size of it V8, l4, large or small capacity, I can't zoom out as much as I used to, maybe I'm just imagining it but I feel like I can barely fit the entire engine in the display?
