Does anyone understand what is going on here?
My aim was to create a sunflower seed pattern. I started with a pair of arcs drawn onto a plane. I then copied them radially a number of times. Then I copied the series of arcs I had created, mirrored them using scaling at -1, rotated them appropriately, and then moved them over the first set of arcs keeping the same centre. The creation of faces between the arc lines is very haphazard. Sometimes you get a face which cannot be painted (the one marked with an X in the screenshot, for example).
I don’t think this is to do with very small things (which I know SU isn’t good at). But as far as I can see, all the lines should be on plane and so should create faces between the lines that define the arcs.
Is there a better way of doing it?
