@Ernie15, I place the board on the ground, save it, and then use Word to edit the piece. Like "bwd,500,429,0.1,5,180" means it's a board at x position 500, y=429, 0.1 thick = 1 pixel, 5 long = 500 pixels and 180 degrees.
The minimum the screen editor will allow you to do is 5 pixels by maximum 300 pixels long. If you want them longer or thinner, you need a text editor to manually edit the code. You also need to keep long horizontal pieces X < 1100 or they will disappear.
