Hi Brian,

re:
> Maybe when selecting a closed curve, selected point/direction does not matter?

Yup, with the flow command if you select a base or target curve by a click it will use the side closest to where you clicked it as the beginning side of the flow but that is only for open curves and not closed curves.

The DashCurve script was inheriting that since it uses flow internally, but when it was flipped that was messing up the trimming part of the script.

Should be fixed now.

Thanks,
