The Crescent Tool can be used to create crescent shapes from the thinnest 'New Moon' shape, to a full ellipse.
Customisation
The Crescent Tool has two options on the shape and on the context toolbar to control the curvature of the shape's left and right sides.
Settings
The following settings can be adjusted using a vertical tool slider:
Width—controls the width of the line using a vertical slider next to the tool's location. Slide up or down to set the width.
The following settings can be adjusted from the context toolbar:
Keep selected—when enabled (default), the new shape layer will be selected on creation. When disabled, the new object is deselected which prevents it from adopting the next object’s stroke/fill properties.
Left Curve/Right Curve—controls the curve of the left/right side of the shape. Decreasing a value moves the corresponding curve to the left, and increasing a value moves the curve to the right.
Mirror—updates the above settings to give a reversed (flipped) version of the current shape.
Negate—updates the above settings to give the inverse (opposite) of the current shape.
Convert to Curves—converts the selected object into a series of connected lines and nodes.
