I'm currently designing a transit diagram in Illustrator CC, but I'm having some trouble with snapping. I'm working on a grid with snapping on, with 10px stroke paths. An example of my problem is as follows: I have a 90 degree path laid out and I go to make a 45 degree diagonal off it using the shift key, but the end of that new diagonal ends up on a half pixel. See the picture below:

Clik here to view.
You'll see the end of the path on the right is at X 630.5 and Y 185.5. I'm working on a 10px grid with 10 subdivisions. How can I make it so it snaps to whole pixels only, this is really infuriating!
