How do you calculate a rolling 45 offset?

How do I figure a rolling 45 offset?

  1. Determine the horizontal and vertical offsets of your pipeline.
  2. Take the square root of the sum of the horizontal and vertical offsets’ squares. This will be the true offset of your rolling offset.
  3. Finally, multiply the true offset by 1.4142 or divide the true offset by sin(45°).

How do you find the offset multiplier?

The equation of this line will be Y = mX + b where m is the multiplier (or slope of the line) and b is the offset(or the y-intercept of the line). All straight lines can be represented mathematically in this way. Calculating the multiplier and offset from a straight line graph such as this one is straightforward.
