Are you using Rhino5? Testing this in Rhino 6 beta gives me the correct result.

There are three ways in which curves can meet:

• They can really genuinely intersect at a single coordinate. This almost always requires either curves in the same plane or curves that intersect at their end-points.
• They can approach each other in 3D space to within less than the intersection tolerance. This is almost always the case for 3D curves that 'intersect' somewhere on their interior.
• They can overlap for some part of their interior, or, to be more specific, the curves will travel alongside each other within tolerance for some significant distance.

The component doesn't output these overlaps, instead it will output points at the start and end of the overlap region. This may be why you're getting two points. But again, in RhinoWip I'm not getting the same result.

What is the Rhino absolute document tolerance you're using while this is happening?

Thanks for your clear prompt response.

It was a tolerance problem. Before it was 0.01 and the previous problem occurred. I changed it to 0.0001 and it's done.

Lots Of Thanks
