I've been using Object > Path > Simplify to clean up artwork but have found that it can create two overlapping anchor points. This adds an extra kink to the path as each anchor point has two control handles. This seems to happen regardless of the Curve Precision or Angle Threshold settings.
Anyone else getting this?
(Illustrator CS5 15.0.2, Mac OS 10.6.2)
1. Simple circle drawn with the ellipse tool.
2. Object > Path > Simplify... applied (Curve Precision 96%, Angle Threshold 0)
3. The two overlapping anchor points pulled apart for illustration
That does appear to be a bug as it immediately says in the simplify dialog that there is five points in the original ellipse when there is actually only four.
I can offer a wy of manually fixing the overlapping points but it is not intuitive and if you have a lot of them tedious but it will fix it.
take the scisso tool make a cut at the anchor point select the the now two end points by what ever means Q will get you the lasso tool or drag the direct select tool and hit command J and you will now only have one anchor point. It does not change the shape of the path.
Yes do not complain to me that this is tiduos and Illustrator is not workable.
This is just a suggestion.
I think you will probably be able to remove unwanted anchor points with Pathfinder (palette) > Unite.
Fist check Pathfinder options (in the fly-out tab). Remove Redundant Points should be ticked in the dialogue box.
This also works if you find you have redundant points on expanded or outlined strokes with round caps, as sometimes happens.
I think I am correct in stating that Pathfinder Unite (when used with correct prefs settings) always removes redundant overlapping points, converting them to single smooth or corner points according to the original direction of the handles. It also removes points on straight horizontal or vertical paths but not on straight angled paths.
Unite is very helpful (thanks Steve) and sometimes cleans up the path completely. There are still times when Simplify adds a whole bunch of points to what seems to be a clean curve. Unite then helps to clean up the mess, but there are often extra points which create kinks or loops in the path. They are easy to miss as you have to zoom right in to spot them.
Also, thanks Wade for the suggestion about cutting the path and rejoining. It’s interesting that CS4 splits the path at the problem point shown above when using Simplify so you are left with an open path. It's as if CS5 rejoins the path but doesn't get the control handles right.
Thanks for the script link, Jesseham. I must look into using scripts more to simplify routine tasks.
I've combined Simplify with Unite into an Action to speed things up. But I’m still using Simplify with caution as often it does just the opposite.

The secret to smooth curves is few points with long handles. So maybe Simplify isn't simplifying after all.
Seldom use it except on very long and complex paths.
