There are a few ways to change the radius of a star in Illustrator. The first way is to use the Radial property. The Radial property allows you to change the radius of a star in an object. To change the radius of a star, use the following steps:

  1. In Illustrator, open the file that you want to work with.
  2. Choose File > New > Vector File and name the file “star_radius.”
  3. Type in a value for the Radius property and click OK.
  4. In another file, open up “star_radius” and type in a new value for Radius. Click OK again to close both files.
  5. Save both files as “star_radius_new.”
