Hello:
I have a case where the left tooth is broken but the right tooth is not. We want to approximate a landmark on the tip of the left tooth by making a curve on the unbroken tooth, cloning it and moving it to where the broken tooth would be. I have my curve, however I can’t figure out how to move the entire curve to the other side (and then mirror its direction).

If you invert the sign of the ‘R’ coordinate values, the curve should mirror by geometry. Then with ‘Shift + left click’ or ‘middle click’, you can move the curve to the broken tooth.

To simplify what @chir.set suggested, you can create a linear transform and edit the first diagonal as -1, create a clone of your curve and put it under that transform.
That’s equivalent to multiplying “R” coordinate with -1 for all your control points (instead of doing one by one).
