thank you fred! i was able to track down what looks like the setting you mentioned in cura 3.1. tricky of them to hide it and post the settings user manual under version 2.0 on their website ha!

so now when i preview the box with the letter carved into it, if set to _concentric_ then that top surface looks all random triangle like. switching to _lines_ it filles in the surface very nicely.

since my letter type face has a circle in it, like a dot over an _i_ that changes from concentric circles to lines as well. it's definitely nice looking with lines, but it must be a or b not a mixture of both.

can't wait to print it again!

EDIT: actually, when i opened the logo box initially, the surface looked nice with concentric lines, like the bottom. it was when i scaled the box +200% that the random triangles appeared. like i said though, lines as the top/bottom pattern look good too.
