The last thing to do is set up the 3D view. Even though all the drawings we produce will be projected into our defined 2D plane, we can look at the plane we are drawing on from any angle (including the other side of the plane so we draw "backwards"). Since we have told it the plane is the one co-planar to the top of the engine block, we should probably have the 3D view looking at that, or at least roughly in that direction. Press the 2 key on the number pad to look at the top view (notice that on the num pad, adjacent keys are opposite views so 1 and 4 are front-back, 2 and 5 are top-bottom, and 3 and 6 are front-back). Once you are looking at the engine from the top down, you can center it by dragging the middle mouse button to pan the view. Finally, the 2D drafting mode will allow us to snap parts of the drawing to the corners of the engine block, the center of the cylinders, etc, in order to make this work best we should hide the crankcase so the drawings snap only to the part we are working on (press spacebar to show/hide the selected object).
