How To Avoid Jagged Lines?

Hi guys,

I am designing a site that uses a lot of irregular shapes, but cant seem to get angled lines to show up smooth. They are coming out very jagged. Any idea how to smooth the lines out? Tips for Photoshop or Illustrator would be great. Thanks!

BTW I don't just want 45 degree angles, but all kinds of various angles. Any help would be appreciated. Thanks.

Making the lines using the Line tool with the anti-aliased option on is probably your best bet.

Err, make sure antialiasing is on for what ever tool you are using to make the shapes (i assume lasso). If you want ot make it smoother use Select > Modify > Smooth to smooth out your selection.
