Insert Labelling
Grid labelling
Insert Labelling: Select this option if you would like each hex to have a label. The label consists of two parts, a column and a row label (e.g. AA01). Lettering counts up A through Z then AA-AZ then BA, etc.
First X label: This can be a number or letter(s). This is the column label (first half of the labelling)
First Y label: This can be a number or letter(s). This is the row label(second half of the labelling)
