fill tool not match spline

[Anonymous]

hello,
I drew a close area including spline, then use fill tool to fill, but the fill area has a little bit discrepency with the spline, which is not so accurate in terms of fine art line.

Please advice
Regards

A fill boundary is only made up of arcs and straight lines, it will try to follow the spline using arcs which will inevitably lead to minor deviations from the spline path. Your Magic Wand setting will impact on the degree of deviation, but never eliminate it.
