Adobe Illustrator Script: Add Circles to Path Points

Description

This Adobe Illustrator script adds small circles to each anchor point of the selected paths. If no document is open, it creates a new document. The script requires at least one path to be selected to run.

Usage

1. Open Adobe Illustrator.
2. Create or open a document.
3. Select at least one path item in the document.
4. Run the script.

Script Details

1. Document Check:

• If there are no open documents, the script creates a new document.

1. Selection Check:

• If no path items are selected, an alert message is displayed, and the script stops.

1. Circle Properties:

• Each circle has a radius of 2.5 units.
• The fill color of the circles is set to RGB (255, 100, 100).

1. Path Points:

• The script iterates through each selected path item.
• For each path point, a circle is created.
• The circle is placed at the location of the path point and added to a new group item within the path item’s parent.

1. Locked Paths:

• Locked paths are not modified by the script.

Example

To use the script, follow these steps:

1. Open or create a document in Adobe Illustrator.
2. Draw or select a path.
3. Run the script to add circles to each anchor point of the path.

(function() {

  if (app.documents.length <= 0) {
    app.documents.add();
  }

  if (selection.length <= 0) {
    alert([
      'You must select at least one path in',
      'order to run this script.'
    ].join(' '));
    return;
  }

  var radius = 2.5;
  var fill = new RGBColor();
  fill.red   = '255';
  fill.green = '100';
  fill.blue  = '100';

  for (var i = 0; i < selection.length; i++) {

    var item = selection[i];

    if (!(/pathitem/i.test(item.typename))) {
      continue;
    }

    if (!item.editable) {
      // Don't modify locked paths
      continue;
    }

    var points = item.pathPoints;
    var group = item.parent.groupItems.add();

    for (var j = 0; j < points.length; j++) {

      var point = points[j];
      var x = point.anchor[0];
      var y = point.anchor[1];

      var top = y + radius;
      var left = x - radius;
      var width = height = radius * 2;

      var circle = group.pathItems.ellipse(top, left, width, height);
      circle.fillColor = fill;
      circle.stroked = false;

    }

  }
