Artlandia, developer of pattern design software, has released Artlandia SymmetryWorks 6, a new version of its Adobe Illustrator plug-in for professional pattern design.

The new version automatically produces balanced counterchange patterns by combining symmetry operations with color reversals. Additionally, SymmetryWorks 6 makes it easy to create all the 46 mathematically possible counterchange symmetries as well as customize color reversals in repeated cells and tiles and introduce instant color reversals within the main repeated unit itself, according to the folks at Artlandia. The plug-in offers both live color inversion and readily customizable harmonic color schemes.

SymmetryWorks 6 requires Illustrator CS6 or the latest Creative Cloud version, Illustrator CC. For users of earlier versions of Illustrator Artlandia provides the previous version of the plug-in, SymmetryWorks 5. The plug-in costs $249 (download) and is immediately available for all Mac OS and Windows platforms. In combination with LivePresets (SymmetryWorks 6LP), the plug-in costs $364.

Regular upgrades from SymmetryWorks 5 and earlier versions to SymmetryWorks 6 and SymmetryWorks 6LP are available for US$75 and $190, respectively. SymmetryWorks can be also purchased in packages with Artlandia SymmetryShop. The bundle pricing starts at $489. More information is available on the Artlandia web site at .
