Astute Graphics are a company that make plugins for Adobe Illustrator. I just wanted to bring your attention to two of their free plugins.
- Circles and Arcs Tools
- Orient Tool
- Perpendiculars and Tangency Tools
- Connect and Straighten Tools
AutoSavior gives you options to regularly automatically save your work in Illustrator.
For each plugin you will need to provide Astute Graphics with an email address so they can send you a free license key.
