How to snap of curve control points to another curve

Is it possible to snap a control point from one curve to another curve? (End to Near)
So that when moving the first curve, the control point always would be glued to the second curve?

This is necessary for “RecordHistory”.
If make a surface on two rails with many curves and edit the basic curves.
If the point moves away from the curve, then the surface turns to crash

Hi leex - no, there’s no tool for keeping a curve end stuck to another curve, you’ll have to readjust after editing the curves.


Hello Pascal!
Can I ask to create this option for R6?

Hi Leex - adding constraints like this will not happen in V6. But…


Thanks Pascal.
I hope.
