Curve/Spline + Utility/Offset

gh offset
gh offset

The offset button in Grasshopper offsets a curve with a specified distance.  The input parameters are: C (Curve) the curve to offset,  D (Number) Offset distance, P (Plane) Plane for offset operation, and C (Integer) Corner type flag.  Possible values: none = 0, sharp = 1, round = 2, smooth = 3, chamfer = 4.  The Output parameter is (C) is the resulting curve.  In my definition I created an elipse as my curve and offset it.  I set a slider for the offset distance to offset it either inward or outward.  Then I divided each curve and created a line between each point created.  I then extended the lines and set sliders to determine the extension lengths at the beginning and end points of the lines.  The final result was an eliptical ring with rays extending from it.
