Illustrator Quick Tips - Constraining Radial Gradients
Have you ever tried to constrain a radial gradient to an oval? It cannot be done in any easy fashion. So how do you do it? Simple... Start with a circle.
1. Draw a perfect circle by holding down the shift key.
2. Apply your gradient to the circle. Make sure the gradient center point is in the center of the circle. This should be set this way by default.
3. With the selection tool grab the handle and stretch or contract your circle to your desired shape.
This is a great technique for creating circular shadows for icons, letters, etc.
