Hatch

Select Use Hatch field on the Hatch tab if you want to make the hatch pattern dependent on the values in one of the fields in the input file. If this option is clear, then a single hatch pattern will be used.

Hatch field

Enter the name of the field (in the input file) that contains the data that will control hatching. The hatch set that is associated with this field maps hatch patterns to text strings or numeric ranges. The value in this field determines which hatch pattern will be used for each record in the file .

Hatch Set

Enter the number (from 1-999) that identifies a hatch file. If hatching is associated with a numeric field, the number will refer to a numeric hatch set. If hatching is associated with a character field, the number will refer to a text hatch set.

You can double-click on the Hatch box, if it is enabled, to define the fill pattern (TrueType Font or TTF) to be used for the hatch.

Hatch Colour Coding

Select one or both of these options to control the colour of the hatch pattern using a colour set. The colours you select will be used instead of the foreground and backgroundcolours in the hatch pattern definition. Select an option then click the More... button to select a colour field and a colour set.

Expressions are supported when specifying foreground and background colour values:

=[Fe_BT_Linear]-[Fe_BT_Ln]		

Right-click in the Colour field response and select Edit Expression from the menu:
