Why are some lines not getting anti-aliasing while anti-aliasing is turned on?

[Daniel Meretzky]

Hi Gurus,



I'm attempting to make a graphic with smooth lines. All the lines are coming out smooth except the one between the brown and white. I have anti-aliasing turned on always. The brown and tan are on a different layer than the white, however, the border between these layers at the top is working just fine.

Can someone explain why this happened in the first place and what I can do to fix it?

Thanks!
Dan

maybe you used a path for selecting, creating, erasing.
paths are usually hard edged.

What tool(s) did you use to create the graphic?

If each line is a separate layer perhaps your antialiasing is not checked in some
