Materials:
There are 12 wall segments that fit together to make the field perimeter. They are labelled on their top side with the following:
AR, AM, AL
BR, BM, BL
CR, CM, CL
DR, DM, DL
The letters signify side name (sides A, B, C, D) and orientation (R (right), M (middle), L (left)).
24 Pegs - These go in the holes to connect wall segments to each other.
Assembly:
The field is a square of side length X meters (Y feet). Throughout the assembly process, try to keep it centered pretty well on the mats so you do not have to move it after.
Pictorial view of 1v1 field assembled (from CAD model)
Each wall segment has a joint on either side (notch with two peg holes in it). Some of these are facing up and some are facing down. Due to this, sides labelled A & D should be roughly identical and therefore placed opposite each other, and same with B & C.
This is a top view of the field with each of the wall segments labelled. The joint direction symbols show how the ends of the segments should fit together.
If you have completed these steps correctly, you should be done with constructing the field perimeter.
