The Arc element in USolver is a powerful and flexible tool for representing curved segments. It can display a portion of a circle or an ellipse, making it ideal for showing arcs, circular segments, or visualizing angles. You can define the start angle and the sweep to control the arc's shape. When used to represent an angle, it visually conveys the measurement and can even be annotated with a value or label. This is particularly useful in geometric constructions, physics simulations, and dynamic system visualizations.
