This circle is a traced object. I want to make it half thinner but I don't want to lose the dimensions. Also there is fill color and no stroke, how can I make it thinner?

I guess with outlined you mean traced, if this is the case:

  • Make a ring (red in the image), a single circle width a white stroke as thick as the desired width, centered to the original image

  • Apply a smooth Roughen Effect to this ring


  • Add a 100% black square frame and send it back
  • Select both shapes and got to Menu Edit > Cut


  • Select the original shape, and from the Transparency Panel click Make Mask
  • Uncheck Clip
  • Click the right square at the Transparency Panel to activate the mask area
  • Paste in front : Cmd + F Mac or Ctrl + F Win


  • Click the left square at the Transparency Panel to activate the editing area





  • You are awesome please help me in few steps step 1 did you created circle with ellipse tool and give it stroke without fill? step 2 i added square shape but what do you mean by cut both shapes? Oct 18, 2018 at 11:57
