Brian,

“”” Performing Flip on a curve reverses the Start and End points.””””

You are well informed. The mis conception is that the command is using the start and end points of the curve.

The command is using the “point you click on the curve” as the info it needs. (Like the flow base and target selection.)

So the reversal is done within the command and clicking your input curve relative to its endpoints can reverse the “direction” of the input.

Sample: loft between 2 curves and while in the loft command, click either end of 1 of the curves.
