As many graphic designers will tell you, one of the most irritating missing features in Adobe Illustrator is the ability to snap to tangents. There are some workarounds for crating tangent lines, but when it comes to more complex curves the two options are generally either manual calculations or making things look “close enough.” But performing mathematical operations on every shape in a complex object is extremely time-consuming and my perfectionist brain simply can’t accept “close enough.” Take, for example, the image above which is a screen capture from an un-finished project of mine. The shape I am creating, while simple in conception, is comprised of many intersecting curves. Normally to create such a shape I’d either have to align the circles manually and hope it looks right or use Illustrator’s “round corners” effect which, frankly, never gives properly accurate results and is a pain to use. Thankfully, I recently found a great free Illustrator plugin that lets you easily create tangent curves using a variety of methods, making the process of creating such shapes much easier. Even better, the plugin covers a wide range of operations that go beyond creating tangent shapes making it a must-have for any serious designer’s toolkit.
