Disclaimer: Not suggesting anyone should actually do this. The point of the post is to demystify the simple prank that is "crop circles" (as the indications are).
It is simpler than surveying 3D terrain with a surveyor's integrity at stake.
The hardest part of making crop circles is coming up with an interesting pattern. Once you have that,
*- Draw it using the CAD software of your choice.
*- Select any arbitrary 2 pioints A & B noting the distance in between
*- dimension all critical points of the design/pattern from these 2 points using aligned (not orthogonal [i.e. not x,y]) dimensions. This will give you the distance of all the critical points directly to each of the two points A & B (two dimensions per point)
*- Find a flat piece of a field
*- Take any point as A
*- Measure the distance AB at any direction to Mark point B
*- Recreate/Mark all critical points measuring with two tape-measures/threads/chains/ropes pinpointing them at crossing points of the measured distances. If point C is 2 meters from A and 10 meters from B, then stretch a 2 meter thread from A and 10 meter thread from B and Mark C when both threads are stretched straight and when you are on the right side of the AB line.
*- then use a board attached to a rope to flatten the field in the desired pattern.
