SnapMeasure is a plugin tool for Adobe Illustrator which addresses several weaknesses of the built-in measuring tool and will tremendously improve your productivity:
â€¢ It clearly snaps with visual feedback to elements on the page (no more measuring three and four times to be sure you are getting the right value!)
â€¢ It can put the measurement values right where your eyes are â€” next to the cursor. No more having to look up to find the Info palette.
â€¢ It lets you scroll or zoom during a measure (no need to make sure the start and end points are both on the screen before you start measuring).
â€¢ It lets you change the color of the measure line, for better visibility on certain backgrounds.
â€¢ It can optionally set and reset the constrain angle and cursor key distance without having to open the preferences window.
