When patterns are applied to satin objects, that pattern will be kept throughout the usage of lettering. It will not be overridden by the automatic pattern filling system in the lettering engine. This allows the digitizer to specify the look of specific elements of the design. This is normally not assigned for lettering, but is an option.
Naming of column objects can affect their adjustment in the lettering generation process. Manual underlay columns, sometimes used to connect perpendicular junctions, should not have additional underlay applied to them during the lettering generation process. To prevent this, rename the column in the object tree. Name them something such as ‘Underlay’ and they will not have their underlay settings adjusted.
