About filling compound paths
You can specify whether a compound path is a nonzero winding path or an even-odd path. Both the nonzero
winding fill rule and the even-odd fill rule use mathematical equations to determine if a point is outside or inside a
shape. The even-odd rule is more predictable: every other region within an even-odd compound path is a hole,
regardless of path direction. Illustrator uses the nonzero winding rule as the default rule. Photoshop and
Macromedia FreeHand both use the even-odd rule by default, so compound paths imported from either of these
applications will use the even-odd rule.
When you create a nonzero winding compound path, you can specify whether overlapping paths appear with holes
or are filled by clicking a Reverse Path Direction button in the Attributes palette.

Circular paths selected, converted into compound path
C.
Reverse Path Direction applied to innermost path
Self-intersecting paths are paths that intersect themselves. You can choose to make these paths either nonzero
winding or even-odd, depending on how you want them to look.

To change the fill rule for a compound path
1 Select the compound path using the Selection tool or Layers palette.
2
In the Attributes palette, click the Use Non-Zero Winding Fill Rule button or the Use Even-Odd Fill Rule

To change a hole in a compound path to a filled area
1 Make sure that the compound path uses the nonzero winding fill rule.
2
With the Direct Selection tool, select the part of the compound path to reverse. Do not select the entire compound
path.
3 In the Attributes palette, click the Reverse Path Direction Off button or the Reverse Path Direction On
button .
