>>@ Tom
Seems you are confused by "Control Points" and Points who are possibly on a curve!<<

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 !!
