Web\$\begingroup\$ To add to this: as you do your routing on a fixed grid, parallel lines will be at least 1 gridmark away. If they make a corner together a 45° angle gives the most space between those two tracks on the diagonal. Different angles may require that these tracks start farther apart to ensure minimum spacing, resulting in less dense routing than optimal. WebThe angle 135° has a reference angle of 45°, so its sin will be the same. Checking on a calculator: sin(135) = 0.707. This comes in handy because we only then need to memorize the trig function values of the angles less than 90°. The rest we can find by first finding the reference angle.
