The Segments frame will also contain controls for segment type-specific options. For instance, the Curve segment type can have one of three different slope forms: Catmull-Rom, Akima, and Bezier found in the Segment, Curve Segment Options frame. Similarly, specific segment options also become available when a Circle or Conic segment is being edited or created. See the Draw Curves section for more details on the segment types and type-specific options.
