On one of my cribbage board carvings I noticed that the outer edges of a region were perfectly rounded from the surface of the carving down to the floor of the region. I really like the appearance and was wondering what caused it. When looking at the carving on the computer I found way at the bottom of the carving list a square box identified as "dishsquare 1". When I delete it the region disappears. I originally designed these carvings and must have done it myself. It must be in the software somewhere; however, I have search everywhere I can think of and can't find it anywhere. Help! Help! Help.
