If you set the concentric dividers to zero (you still get a backing circle which can be deleted by ungrouping the path and deleting the circle) and setting the radial dividers to say 40 - you get a starburst or star in seconds. Once you have the starburst design, you can then add other effects etc to the artwork

As this is Illustrator, you don't need to stop there and you can apply live effects to the lines as well as variable width profiles (option bar) or brush strokes.


Select all the generated lines of the polar grid (though you can select alternate lines or perhaps the top set of lines). Set the color of the stroke. Go to the variable with profiles. Select one such as width profile 4. Expand apperance via the object menu Select all paths. Go to the pathfinder and Unite


zigzagYou can then add other paths to the design such as a circle to the centre of the generated polar artwork and then selectboth and then select the minus front in the pathfinder panel (image on the right)


Select the lines of the ungrouped polar grid. Go to the width profiles at the top of the screen and select the width profile 4

Set the color of the strokes. Go to the effects menu and Twist and Set to 45 and click Ok.

Many different radial designs can be created using the polar grid tool as a start point. You can then add effects to extended them in countless ways and as effects are live until you expand them, you can edit the artwork over and over. You can also simply store the artwork as a new symbol for additional presets or perhaps add it to the CC libraries for use in AI as well as Photoshop and After Effects and Premiere for example


solar lookYou can also use the polar grid to create the design and then add brushes to the generated artwork.


As brushes can be any kind of design, many different interstellar designs or galactic artworks can be created in seconds and they can then be extended either further or expanded or re-colored and more


As with above, you can create a very basic stroke design but instead of adding a width profile, you can add a brush. You can use your own brushes, you can use the brushes supplied with the application and so on.


Create a red circle. Create another red circle but make it smaller and place a distance away from the first circle. Select both and align horizontally. Go to the blend tool and double click and set the spacing to steps (say 5. Click the first circle and then the next with the blend tool. Object menu and expand and display the brushes panel. Drag the paths into the brushes panel and Set to artistic and click ok


Go back to the generated lines. Select them and Apply generated brush by selecting it in the brush panel. Object menu and expand appearance and Pathfinder and unite


Or just create a path using the curvature tool such as a wavy / curved design and then add that to the brushes panel. Apply the wavy / curved brush to the generated artwork. You can also then add variable width profiles to further modify the artwork in even more ways such as applying a width profile one to the strokes. You can also use the width tool to further modify the work
