Hi Tom, I took a look at your file but there's 31 curves in it so I'm not sure where I should be looking for the question you had here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=8468.9
Could you please simplify it and only have the curves in it that you had in your screenshot with the green arrows?
Certainly it is going to be difficult to manage so many curves all needing to intersect each other with everything swooping around in 3D at the same time. It might be better to use a smaller number of curves if possible like only focus on ones in one direction and loft between those or something like that.

<< If you use Edit> Separate on the polyline it should then work like you're asking I think.
Yes fine!
If i good remember when 2 points or more are overlaped in the same x,y,z
there was a red square... but don't remember in what Function(s) and if it's always living! :)
@ Tom
Seems you are confused by "Control Points" and Points who are possibly on a curve!

The red square is if you have 2 of a single curve's own control points (the points you see if you select one curve and use Edit > Show pts) stacked up on top of each other. That has to do with the points just in one curve, not anything about multiple curves touching each other.

So here reduced to 2 curves.
There is a tiny gap between them.
How do I achieve that the grey one will share an overlapping point with
the red one ? I have no point to pull, so I move the 2 nearby points
with the nudge commands visually till I guess the gap is gone.
Is there a way to let MOI tell me - yes the gap is less than 0,000001 now ?

Hi Tom, can you please post the 3DM file too?

Its difficult ro differentiate, I agree !
When I say "curves with a common point" I don´t mean a literal curve point but the
same coordinate.
I hope the files and the screenshots can clarify my topic

Hi Tom, so one way to do it would be to put in a dividing line down the middle of the gray curve, use Edit > Separate on the gray curve and then use Edit > Trim on the lower part of it to split it into 2 pieces:
You can then join the pieces together and there will now be a point that's directly on the grey curve which you can place on the red one, you'd grab that point and the inner 2 so that they all move together and keep the pieces smooth with each other:

Sorry no there's nothing set up in MoI to monitor curves for proximity after nudging like that.

Ok very good, so this confirms that there is always a REAL point needed for exact placement of a curve
onto another one.
Muchissimas gracias again Michael - the MatchingScript is a fantastic time saver !!
