Enhance Adobe Illustrator's measuring tool
Measuring items in Adobe Illustrator is an exact science but it isn't made particularly easy by the application itself. SnapMeasure brings more accuracy to the measuring process.
If you've ever measured something several times with different results each time, then SnapMeasure will probably be useful. SnapMeasure uses Smart Guides which can "snap" to points by highlighting them on the image. Rather than having to squint for the Info palette, SnapMeasure places values next to your cursor so you can make accurate measurements far more easily.
You can choose to display the values continuously or just afterwards. You've also got control over how much information you want to display and even the appearance of SnapMeasure by changing the size, color, and more. You can also set the angle and increment values. One final bonus is that, on hard to see backgrounds (such as grey for example) SnapMeasure allows you to measure in a bright red line making things much easier to see.
SnapMeasure is an essential tool for anyone that measures lines or distances in Adobe Illustrator regularly.
