Alternate and Winding Fills

[Markcq]

What are the possible reasons for the Alternate and Winding Fills to be greyed out in the menu?

I'm following instructions from the help file:

When I try it, I cannot select either:

I've tried with nothing selects, with only one object selected, with two objects selected. I've tried selecting directly on the artboard as well as from the layers menu. Am I missing something or is the help file just sketchy?

Ok, so I finally found that I had to convert to curves or draw something with the pentool to activate the menu items.

But now, the two options look the same...

Hi Markcq

The fill mode applies to singular curve objects, not multiples. This is why you're seeing no difference when changing the fill mode currently. As can be seen in your first post; 

Filling self-intersecting shapes

Shapes which have been constructed using self-intersecting lines can be filled in two different ways.

I've created a quick video below showing this, I hope it helps clear things up!

Thanks, that's amazing... Strange... the orange examples I have above was done with a single curve... I have tried it now and it works. Not sure why the previous one didn't work. Thanks for the vid. Really helpful.
