How to turn a path with straight lines into a curved path automatically in Illustrator?


I know how to do this manually, but I need an automatic way (either a script or just a command in Illustrator).

Here's a line like the one I mean. Notice how it's all made of straight lines (The blue dots are the anchor points):

How can I turn this into a true curve easily?

Note that I have all of Adobe Creative Cloud at my disposal, so if there is a tool in Fireworks, Photoshop, or anything else that can help, it is still relevant.

Accepted Answer

You can try Object > Path > Simplify and adjust the Curve Precision and Angle Threshold settings to perhaps get a curve.

There's no straightforward method, which I'm aware of, other than this.

There's also the Smooth tool enter image description here if you prefer a more hands-on approach. Rub it over a selected path, and it smooths it where you rub. If it doesn't smooth enough, keep rubbing.

From this tutorial:

enter image description here

Double-click the tool icon to set how closely the smoothed line sticks to the original (fidelity) and how strong the smoothing is each time (smoothness).

A nice additional feature of the smooth tool is, it only applies to paths and points that are selected. So, if there are parts of a path you want to stay exactly how they are, and parts you want smoothed, you can select just the points you want to be smoothed then use the smooth tool.
