I made something like this:
I did this with the Ellipse Tool and the Line Tool.
Now the circle is accurate, but the lines inside are very inaccurate. Is there another tool that does the same thing but with a lot more accuracy?

Surely this can be done by warping a set of rectangles around a circle, as with circular text?– SuperbestCommented Apr 12, 2016 at 0:03

- Draw 2 concentric circles
- Draw a connecting line (w. line tool for example)
- Enable rotate tool (with line selected) and alt click on the center of circle.
- Type in a value in degrees that is a divisior of 360 (2, 3, 5, 6, 10, 15, 20 etc)
- Hit duplicate
- Keep hitting ctrl+d (repeat last) until a full revolution is done.

The advantage of this method is that it has least cleanup and it would work for cases where you can notdraw a line trough the cented for some reason.– joojaaCommented Apr 11, 2016 at 7:34

yes this method is a straightforward solution. while most of mine are "Cumulative Solutions" ;)– hsawiresCommented Apr 11, 2016 at 7:42

1@hsawires yeah well i had to compile the screen capture also, so i dont have time to think about more complex things. Lies– joojaaCommented Apr 11, 2016 at 7:43

2This also has the advantage that you don't have to use lines. You could use little arcs for example ;)– PieBie ♦Commented Apr 11, 2016 at 8:00

1Illustrator supports simple calculations in the input box. If you don't remember the correct number of degrees simply enter "360/n" where n is the desired number of pieces.– PhilCommented Apr 12, 2016 at 23:42
Please follow these steps:
- Draw a Line from the line tool or press \
- Open
appearance panelor press SHIFT+ F6 - Apply the hereunder setting, those setting will array the line "Polar Array" we will copy the line over itself and rotate each copy
10°and we will copy it 17 times. You can adhust the values the way you want it.
- Now we will draw two circles on for the external boundaries and one to hide the center of our last array.
That's it

yes well now make the lines slanted so that they dont go trough the center ;)– joojaaCommented Apr 11, 2016 at 7:33

There is by the way two solution that hawen't been suggested yet. Its to use the blend tool with a circular spine to make the ladders. It has the advantage of working also on other shapes such as ovals or random forms. One could also do this with auser defined pattern brush– joojaaCommented Apr 11, 2016 at 7:51

2And another simpler solution is to make a dashed stroke circle and give it a width.– hsawiresCommented Apr 11, 2016 at 7:53

And another one could use a wrap envelope to bend a straight form into the circle (or a half in fact). Which would make certain task easier.– joojaaCommented Apr 11, 2016 at 8:11
This is not the fastest method, but it is the easiest to understand for novices. And has these added advantages:
You can make unequal parts as well as equal parts. Just input different numbers in the pie chart data dialog.
When using Divide you can keep the inner parts if you'd like to use them later on in your design.
Get yourself some pie. Then open the pie chart tool and create a pie chart with the desired number of 'blocks'.
OPTIONAL Make a duplicate of the pie chart and hide the original. This way you'll have a back-up if anything goes wrong later.
Ungroup (ctrl-shift-g) the pie chart.
Create a circle the size of the desire hole in your soon-to-be doughnut chart. Position the centre over the centre of the pie chart.
Select both ungrouped pie chart and circle and use minus front from the pathfinder dialog. Or use divide to keep the pieces if you want to use them later or if you want more control.
Delete the parts you don't want. Sometimes you need to do a little cleanup.

2This is by far the most convoluted method. But is has one advantage you can easily make the areas unequal.– joojaaCommented Apr 11, 2016 at 7:36

yes, this is another nice methods. How could a simple question may lead to so many solution ;) nice job.– hsawiresCommented Apr 11, 2016 at 7:44

The other methods can also generate the inner shapes with no problems there.– joojaaCommented Apr 11, 2016 at 7:46
Another Smarter answer (just to enrich the answers) to use just one circle and to take advantage of the appearance tool.
- Draw a simple circle
- open the appearance panel by going to
Windows > Appearanceor just click SHIFT + F6 - Now select the circle you have just drawn and make the herunder setting, or just make the values that you want. make sure to click on dashed lines and add the values that you want.
- From the
appearancepanel add a stroke by clicking theAdd New Strokebutton and uncheck the dashed button. - we still on the
Appearance panelnow step over the last stroke that you have done and click overDuplicate Selected Item, this step will make another strok exactly over the last one you did.
- Now we will scale both last two strokes to wrap the dashed lines of the circle.
- We still on the
appearance PanelSelect the first stroke and clickadd new effect > Distort & transform > Transform ...and adjust the values the way you want.
- Repeat the last step of the other stroke but that time with minus scale values
- after all it is just one circle with three different strokes style. go to
View > Outlineor just click Ctrl + y to activate the outline view. You will notice it is just one circle.

2Perhaps it would be better to use Effect -> Path -> Offset Path... instead of transform then it would work in shapes other than a circle– joojaaCommented Apr 11, 2016 at 8:39

you know ... I was thinking of a diagram to show the different ways to accomplish this task ;) ... so many alternatives.– hsawiresCommented Apr 11, 2016 at 11:56

What about starting off with Polar Grid? Really surprised haven't seen that suggested. Double click on the tool and type in the number of Radial dividers. Very quick - ungroup a few times, divide or shapebuilder tool (with alt to remove)and thats it.
