To understand and verify the offset distances you can create a dimensioned layout of the existing hatch pattern. To fully understand this I have illustrated each character set. *HBFLEMET,Brickworkflemishbond Free patterns from 0,0,10,0,150,215,-122.5Įach line of code represents a line in the hatch pattern.
