I would like to add circles (eg) to each corner of a path.
I can make it easily if I break my path into separate segments and use arrowheads, but I would prefer to keep it one single path.
I have tried using a pattern brush, but the shapes are deformed, some of the corners don't show if the angle isn't sharp enough. (I have also tried with a dotted line, rounded path ends and 0mm dash and long gap eg but it doesn't work if my segments are different lengths).
You could try this, the circles are separate from the path, but can easily be moved together with the corner when selected with the direct selection tool.
Select your path and choose: Object > Direction Handles.
Hi Ton, thanks for your reply, but I already have several workarounds. I'm looking for a solution where the circles are part of the path, as I'm creating many paths and have to move the anchor points often. Maybe it's not possible, but maybe there's a way I don't know yet about. 🙂
Yes, I'm looking for a solution where the circles are part of the path, as I'm creating many paths and have to move the anchor points often. Maybe it's not possible, but maybe there's a way I don't know yet about. 🙂
This is probably easily done with a script - I say probably because I'm not a scripter - but you will have to keep invoking the script, or wait 'til you've completed your path then run it.
Not a solution but a clunky work around: draw your line, apply the circle arrowheads, with the direct selection tool select every other line segment, cut, then paste in place.
There's an Align box under the arrowhead section of the stroke pallet, which will change where your line starts. (I used the first one and the circles perfectly overlapped - if you are concerned about them not overlapping just have the circle arrowhead turned on on one end (except for the first (or last) line segment where you'll need both) - the problem with this is you really have to pay attention to the stacking order so that the "tail" of the previous line segment is under the circle.)
as far as I can see, Crooty already stated in his initial post that he knows workarounds that split the paths into separate segments. At the same time he said that he would prefer something more compact.
Therefore I provided the pattern brush approach with circular tiles that do not get distorted (which usually happens if one creates tiles out of normally drawn circles). The downer at the moment is that it doesn't work well with some obtuse and acute angles. Nonetheless, it will work in many cases, though some manual work will be required.
It is possible that I misunderstood the question, but if the intent is to add a circle at each anchor point, then this is trivially simple with a script. Select a path and run the script. The diameter and stroke weight of the circles can be changed by changing the values in the first two lines.
// select path
var diameter = 10;
var strokeWidth = 1;
var points = app.selection[0].pathPoints;
var items = app.activeDocument.pathItems;
for (var i = 0; i < points.length; i++) {
var top = points[i].anchor[1] + diameter/2;
var left = points[i].anchor[0] - diameter/2;
var circle = items.ellipse(top, left, diameter, diameter);
circle.strokeWidth = strokeWidth;
circle.selected = true;
}
app.executeMenuCommand("group");
basically you understood the task pretty well and there are already a couple of scripts out there that do similar things. As does the the approach Ton provided.
But if you carefully reread Crooty's request, it is pretty obvious that he is not looking for a rather one-shot static solution. As far as I understand, some kind of compact dynamic objects are desired, such that you can for example just continue the zig zag paths or add and move some more anchor points while the circles will automatically be added. The scripting route cannot do that. The pattern brush can do it (with some limitations I mentioned above).
well, the scripting route could add circles to every path point as well.
But as you said, this is not dynamic.
FWIW: Once I tried something like that with InDesign.
Made the script dynamic by adding event handlers with an "Idle Task". Something, I think, one cannot do with Adobe Illustrator. At least not with ExtendScript. My script for InDesign was not very fast, that's the main thing I disliked and needed always an idle moment so that the process could follow up the path points, their new positions and possible new or removed path points that had to be calculated.
