Almost. Actually, I drew the roads grid first. Then, I filled one of the diagonal spaces with a rectangular field. But then, I had these pointy edges of the rectangle piercing the next adjacent diagonal space. I cleaned this up by drawing roads over them such that the parts of the field I didn’t wanna keep got deleted. Finally, I deleted these “auxillary roads” again. Then I proceeded like this with all diagonal fields.
Appreciate your comment, thanks
