Unwanted deformation using Flow along surface or Apply UV Curves

I’d like to get the following 2D drawing flowed on the white surface (sail).

The result is too distorted (the cross should be about the middle and the vertical lines should be distributed regularly):

How should I proceed ?

Hi Alan - make a temporary target surface by rebuilding the actual one fairly densely - say 50 by 30, Rebuild command. That will have nice even parameterization that will make the flow a little nicer - you can delete the rebuilt surface when the flow is done.

Perfect, thanks :slight_smile:
