Create Intersecting Arcs

What happens here

Now, using one of the equidistant points as your pivot, extend your measuring tape to a length that is greater than half the distance between your two equidistant points (e.g., if the equidistant points are 6 feet apart, use a radius of 4-5 feet). Hold the end of the tape measure at your pivot point. Use the spray paint wand to draw an arc above and below your working line. Repeat this process from the other equidistant point, using the exact same radius, to create a second set of arcs that intersect the first set. This will form two distinct 'X' marks: one above the working line and one below. The video clearly shows the sweeping motion with the tape as a compass and spray paint to create these intersecting arcs.

Goal: Generate intersection points for the perpendicular line.
