Adobe Illustrator 2020 compatible: update :-)
All Graffix plugins for Adobe Illustrator are now optimized for Illustrator 2020 for both Mac and Windows, and available for download, with the exception of ServerLock. That update is in progress. IsoTool is not updated, but its functions are now built into AxoTools — The drawing tool from IsoTool will continue to work for free in AxoTools without licensing.
