2d offset - controlled output

It seems that the offset component sometimes produces unpredictable results, so I decided to create a workaround.
The definition is far from perfect (no kinks allowed yet, for example) but produces a fast and accurate result for many curves. In addition it will produce multiple resulting offset curves in cases like this:

 
 
You can't achieve this result with the standard offset component nor the offset command in Rhino.

It generates the set offset curves and some of them will inevitably be junk. I 'discover' the junk by inserting one point on each curve and check if the distance to the closest point on the original curve, is the actual offset distance, if it's not due to junk geometry it's culled.


As Nik show it's possible to give it geometry that will fail.

Perfect. Thanks
