The Segment Tool makes it easy to create an ellipse with a percentage removed as a section.
Customization
The Segment Tool has several options on the shape and on the context toolbar to enable the percentage removed from the upper and lower section of the ellipse, and the angle of the ellipse to be controlled.
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.
Angle—sets the shape's starting angle.
Lower Line/Upper Line—controls the position of the shape's two straight lines. This determines the thickness of the segment.
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.
