Hi 3image - that's not an edge in your file there, it's a "standalone curve". An edge is part of the trimming boundary of a surface.

You can merge your curve's segments together by turning on control points and deleting the point at the juncture, or by using the Rebuild command on it.

Probably in the future I'll try to combine optional merging into the regular Join command but I still haven't entirely worked out the details yet.

Ok ok now I understand. :-D

I now see that this function works for broken edges in faces and objects. I always thought it handles faces.

So it's everything clear now. Sorry for bothering.
