I am desperately trying to make a spiral (see picture below) narrowing out at the end. The line should be thick at the beginning and become very thin at the end. It should be a very smooth transition. I tried brushes, which works well but it does unfortunately NOT work with a gradient. And I need to apply a gradient on my object. The width tool does not work as well (see pictures below), as it seems to work only between anchor points (although I have joined the pathes...). How can I reach my goal to have a tapered spiral with a gradient applied on it?

Many thanks for your much appreciated comments.

Best regards, Silvan

  • What didn't work? You need same spring with similar gradient but it should keep getting narrower?

  • Width tool seems work fine, if I correctly understand what you want to achieve.

You may not need the actual Width Tool.

You can simply set a Stroke Profile in the Stroke Panel for many things. Then use the Width Tool if you wish to refine further.

Like you said, gradients don't work on a stroke with art brush. However, width tool seems to work fine to me:

I can reproduce your problem following way. Applying a small amount of Width tool somewhere middle of path or near one end, and then applying it at extreme end:

EDIT - After checking the OP's open file, I found this:

Here's what was causing problem:

enter image description here

As you can see, two anchor points were going in opposite directions and once I moved them in 'proper' place, Width tool worked throughout the stroke. You will need to find and fix all those anchor points. I guess the they weren't joined properly in first place. So it caused problems.

Another way of doing this is by making a raster image like this and add it to art brushes and then applying it to your stroke:

But it will have some limitations like you might not get smooth result and you won't be able to edit colors.

  • Thanks for your answers. I dont know why but width tool doesnt work with my form (see pictures below). It changes only size between anchor points. Why is that?

  • @Silvan I think the problem with your path is they are not joined. Are they two seperate paths?

  • I posted a picture few seconds ago. I marked all the paths, went to object -> path -> join. but it doesnt work with the width tool...
