Something I have never seen before. In the attached file I have two splines. If I try to run GCON, rhino always says "Cannot evaluate curve.’ when I click on the curve in read.
Why is that?

There are 2 superimposed control points… Just delete one of the two and _Gcon works… probably the curves were generated starting from reference points and drawing them the end point of the red curve and the initial point of the violet curve that coincide was used.

Thanks for the diagnosis. I have found that I am creating such curves when I do INTERPCRV and use the N option at a curve with a point at the end. I don’t get the problem with the S option going the other way.
