Radial designs using polar grid tool in Illustrator tutorial

How to create interesting radial designs such as pie slices in Illustrator using polar grid tool tutorial

Generate radial designs

radial polar grid designs in Illustrator tutorialYou can generate a pie slice or radial spokes by setting the concentric setting to zero (though weirdly it does still generate a single entry) and you can then set the radial to any number of spokes you wish to generate a pie slice or spokes (you can always remove the circle by ungrouping the path and then deleting it). You can set the color of the slices, you can tweak the lines and much more to create all kinds of wonderful line art


The image on the left uses the lines from the polar grid and then set the color and width for each to a random value


Radial pie slices for the polar grid in Illustrator

radial pie slice designs in Illustrator1. Go to the polar grid tool

2. Double click the polar grid tool icon to display the options

3. If you want to create just slices then set the concentric dividers to zero.

4. If you want 14 slices in the polar grid, enter 14 into the radial divider field. If you want a circle of 40 slices, enter 40 into the radial divider field. The limit is 999 which does result in a pretty narrow slice.

5. The polar grid slices can also then be manipulated further by using the ungroup command found in the object menu.


The result of the ungroup being a solid circle and a set of lines (not slices). To turn them into slices, use the live paint tool to fill all the slices with the same color or different colors and then move the slices to different positions.


It does require a few additional ungroups to get at the slices or you could separate all the slices by using the isolation mode (double click the polar grid). On the right, you can see the pie slice applied by ungrouping and then dragging the individual paths to a different position

Multiple polar grids and radial designs

polar grid color fill in Illustrator radial designYou don't need to just create a single polar grid path, multiple polar grids can be created using the tool. The settings can be varied for each of the grids and then all the grids can be aligned to a single center and then ungrouped to create a more colorful radial design


  1. select polar grid tool

  2. set concentric to 0

  3. set radial to 15 and apply

  4. go back to the tool settings and set the radial to 12

  5. create a new grid on top of the existing one but smaller

  6. select both

  7. live paint bucket

  8. select colors from a swatches library

  9. go to each cell of the polar grid

  10. expand live paint


The radial polar grid can then be re-colored using the color guide or color adjustment tools in the edit menu

Polar grid tool radial contours

2. set the concentric to 0

3. set the radial to 15

4. apply the polar grid in Illustrator

5. object menu and ungroup

6. delete outer circle

7. select all the radial strokes

8. set the width to 12px

9. object menu and expand

10 pathfinder panel

11. unite

12. object menu and path and offset set to 10

13. change color

14. repeat offset

15. change color for that offset and so on


A variation of this can be using the corners feature on the selected lines to create a rounded initial path and then use the offset filter with the round joins and use the direct selection tool and the corner feature to round the corners of the polar grid design and repeat the offset
