It was created with Alibre http://www.alibre.com/
And then printed/published to .pdf
Been using it for a few years now. It is a full parametric 3-D Modeling program. What you are seeing is just a saved screen shot of the sketching area with all the reference (grid, coordinate) toggled off.
I use it to create detail drawings for my shop and customers.
I forgot to mention that you can fly around the drawing I posted. Just click on it.
