◦ 
—Performs one of two mutually exclusive operations:
—Performs one of two mutually exclusive operations:▪ Switches the side of the trimmed object to keep, cycling between one side, the other side, or both sides, when Thicken trim is not selected.
▪ Selects the side to which to apply a thickness value, when Thicken trim is selected.
◦ 
Silhouette Trim—Trims a quilt at the silhouette of the projection of the trimming object in a normal direction onto the quilt. Available when the trimmed object is a curved quilt, and the trimming object is planar.
