Sketch Create groups its drawing tools under Line, Rectangle, Circle, Arc, Slot, Polygon and Spline. Each family's main button starts the part's last-used variant and its caret lists the others; choices are per open part, kept across sketch sessions and tab switches, and never touch the design or undo history.
