Curvethroughpolyline

Hi guys,

in brief, I noticed that the _curvethroughpolyline command gives a different result than a grasshopper definition made to do the same. 

In the picture you can see that the grasshopper result gives a wrong vertex in the left, also if the periodic input is setted "true".

How should you suggest me to obtain a _curvethroughpolyline result in gh?

many thanks

:::SOLVED:::

To obtain the same result you have to cull the last control point of the poligon, which is a duplicate of the first. Then you run the nurbs component with periodic setted "true".

Thanks

A closed polyline has coincident first and last points. Try removing the last point before fitting a curve through it.
