Arc Reactor

Arc Reactor is a basic utility for editing arc data in Figma. Instead of using percentages, you can select an ellipse to:• Set radius values in pixels• Set sweep start and end values in degrees• Set zero-degree origin at top, right, bottom or leftArc Reactor gives you more precise control over arcs and converts these values automatically.

If you select an ellipse, your changes will apply to that selection. If no ellipse is selected, a new arc will be created for you.
