Take this image for example:

How would you tackle the task of continuing the curve (left shape) till it joins with the second shape in a 'more precise' way than taking the pen and guessing the angle/curvature?

I usually end up redrawing from the last straight anchor points:

  • Its possible to extend a bezier curve, now i only have t-param extension would be better to extend by length parametrisized bezier domain, but i dont have a clue on how to do that so... you can find more on the subject in this post. It might work well or not (but that's normal, right). IMPORTANT: copy the bezier segment to extend! PS: let me knw if thsi could be an answer for you

Here's one method that might work for you if you have Illustrator CC.

Use the Curvature Tool.

Use of the curvature tool screen capture

The result looks pretty smooth, and done without the need to mess with Bezier curve handles!

Finished result

The Curvature Tool is a fairly new feature, Illustrator CC October 2014 release, and later.

  • Hey, yeah, this works nicely but I don't have CC. My version is CS 5.5 Extended therefore I don't have this feature. Probably should've mentioned the software version but +1 for a nice feature that will benefit other readers that have CC. :D

  • @Alin Ok, so perhaps it would help if you created a couple of bezier paths and turn these into guides before you attempt the edit. See example here imgur.com/aOOYTki guides are highlighted red, That would certainly take some of the guesswork out of it.
