One caution to using high segment counts for arcs and circles. You can very rapidly bloat the file size and degrade computer performance that way. Keep in mind that once you've made a change in the segment count for the model, it will remain at that setting. While you might want a high segment count for the edge of a table or counter top, you probably won't for a bullnose or other rounded profile. If the curve is small, you won't notice that it is made of a small number of segments. You probably won't need to set the segment count anywhere close to 1000 for the appearance of a smooth curve. Maybe around 100 would be plenty.
