ClosestPoint( <Path>, <Point> )
Returns a new point on a path which is the closest to a selected point.
Note: For Functions, this command now uses closest point (rather than vertical point). This works best for polynomials; for other functions the numerical algorithm is less stable.


ClosestPoint( <Line>, <Line> )
Returns a new point on the first line which is the closest to the second line.
