I'm using Illustrator CS5, and I'm trying to have two groups (with multiple paths in each) overlap properly.
On the top side, group A should overlap group B, but on the bottom side, group B should overlap group A.
The only solution I can come up with is to Knife-cut it in two, but then I get ugly cutting lines I can see in the result, even if I don't move the parts away from each other.
This will hopefully make it clear. I want the arm to be over the t-shirt at the bottom, but under the shirt at the top.
