Path

How can I take an arbitrary shape in Illustrator and move all the points outward until they fit a circle. I was looking at blend shapes, but what I really need to export a version of the shape that looks like a circle and another version that looks like this with the exact same number of points. So when they are both exported as an SVG, I can animate between them with web animations.

I also looked at "Add anchor points" to try to match, but the number of points it adds is not controllable.

  • You can use the Pen Tool to add anchors to any path. (Or the, uhm, Add Anchor Point Tool - which is under the Pen Tool.)

  • Start with the circle. Add points as needed. Then distort circle into random shape. Commented Sep 1, 2023 at 23:10

Your example shape has eight anchors, so as long as the circle has eight anchors, you should be able to make a reasonable step blend to interpolate between the two. Here's a possible method.

  1. Draw a circle on top of your shape

  2. Add anchors to the circle (Object > Path > Add Anchor Points). This will increase the number from 4 to 8 anchors, i.e the same as your shape.

  3. Select both the circle and the shape, and create a blend, edit the blend to make it a step blend and increase the number of steps.

  4. Double click on the blend to enter it, and select the circle.

  5. Rotate the circle a little until you get a smooth transition.

  6. Expand it to bake in the blend as separate paths/objects.

Here's an example showing how much I rotated the circle in step 5 above.

  • I also had to make sure the paths were in the same direction and the starting anchor points more or less in the same place Commented Sep 6, 2023 at 17:42
