Weld won't weld

Something else: Anything on other invisible layers?

I mentioned Vertex Tools above. That is not the plugin I meant. Let me search, and return here.
Edit: I meant to say ThomThom's Edge Tools. It is free, whereas his Vertex Tools is not.

Little bits of branching lines or tiny gaps will stop everything welding into one curve.
Occasionally some curves/arcs and other edges just refuse to weld into one - you must appreciate it is a complex task to take all of the bits of connected edges and curve segments and arrange them into a logical order so that they can form the new single curve.
If I get this problem I usually explode the awkward curves back into separate edges and then all of the selected loose edges will weld into one curve provided there are no 'branches'...

Just because I joined before you doesn't make me any smarter than you
Thanks for your ideas, I think you could be right with little gaps or add ons
One thing that was odd if I copied the curve and welded it , it would weld, then I move it to another line it would 'unweld', hope that makes sense

I merely meant that maybe you had come across something like this before and my response had already been tried. I did not want to waste your time with non-relevant data. Like that below:
Smart= Intelligent? Innate but untried?
Smart= Shrewd? limited intelligence but focused like a snake?
Smart= Wise? intelligent and older?
Smart= Experienced? been there but hasn't learned?

Back on topic: It is odd that behavior you mentioned about copying and moving.
Perhaps this is a method you might use in future when the same circumstances arise. I do not have a clue. Well, I have a clue but I cannot verbalize it right now.

It would be interesting to see the SKP file with the curve that won't weld.

I didnt mean to sound sarcastic, it took me years to learn some things in SU
I appreciate your help
Heres the file its the curve by the arrow
Thanks

Ok, I zoomed in to clipping and saw that you have some redundant segments branching off of at least one curve. One of the curves in the path has a total length of ~196mm with about 9 segments. I think this is the one with the branch.
So, TIG was right.
Also, I believe you will need to take away that slab that the curves are engaged on.

Thanks for posting the skp as v7. Maybe update your profile to show your version, etc. unless I missed it somehow, I wasn't sure I was going to be able to open it at my current location.

Edit: You may want to scale the geometry up a few 10's of times so that when you do the infill mesh, you do not get the tiny unfaced triangles.

Thanks mitcorb & Tig

Glad to be of assistance. Also, some short sections(arcs of two or 3 segments) of the curve path seem to have chords forming faceless slivers, the distances are so tiny. Again, this can be seen when you zoom in to clipping.
