Pattern design on Illustrator

Check and Plaid Patterns

Check and plaid patterns are also easy to create with multi-replicas that save you a great deal of the work of manually duplicating and arranging repeating elements (here, lines). Better yet, when you want to make a change, you simply edit one line and the plug-in instantly updates all the repeating copies. As usual with SymmetryWorks, you immediately see the effect of your edit on the entire pattern.
