Tool for dividing a circle into slices?

[anna-kaisal]

Is there a tool on Illustrator that can EASILY divided a circle into 52 equal slices?

I have been struggling with this matter for some time now and I have a dead line coming.

Here is a youtube video you can follow How to Divide a Circle into Equal Parts in Adobe Illustrator - Quick Tips - YouTube

i'm pretty sure this is what the video describes, but I can't watch it here, so just in case.

draw a path from the centre of your circle to the outside. use smart guides to align it to the centre.

use the rotate tool. with just the line selected, alt-click on the endpoint at the centre. type 360/52 into the box and tab out. this should give you 6.92 degrees:

click 'copy'. hold down ctrl+D (transform again) until you have lines going all the way round:

select both lines and circle. use pathfinder - divide.

Thank you for useful advice with great screenshots   Got my  work done !

There is however a mismatch, probably due to rounding of numbers which illustrator does.
If you also do the last one, so it should overlap the first one. In outline mode we see a mismatch.
small gap, meaning a mismatch

I found this by using a different method.  I tried a method using the "Pie" slicing options. I noticed this showed a mismatch end, a gap so to speak. Then tried this method and again, same mismatch and a gap

again same gap, using pie slice options

I used the same number; 6.92deg I even tried 360/52 to make sure it was exactly the same
Pie slice settings

All nice and dandy that illustrator says it can do math, but its not reliable. See what a calculator comes to with same 360/52

Issue with illustrators math and rounding of numbers

Issue is kinda fixed by using a float of 3. so paste in this number. Illustrator again rounds it, but now to 3 decimal.

6.923 gives much better result

No visible hole at regular zoom

schroef,

I have the opposite experience, so I always leave calculations to Illy (job description Adobe Illustrator) and just draw, without even looking at the often inevitably rounded number presented in the (ir)relevant box.

There are a few functions with inbuilt coarseness/inaccuracy. I wonder whether the Pie is one of them.

May I ask what happens if you use rotation by Transform or Effect?

[schroef]

I did not try that. I believe the calculations in general cause this. It rounds to 2 decimal numbers. Which in this case, causes the mismatch. With a 3 decimal number, it's almost perfect match

The Transform Effect seems to do a better job.

First time I checked with the Rotate tool and found the result slightly off. The Transform Effect was accurate.

Tried again today and both ways were accurate. Maybe wednesday is a bad day.

In Kyle of Lochalsh there was a pizza baker called Jack who cut in one whack.

Just for fun.

Nice slice! That must be Jack from Pizza-Mia, Ferry Rd, Kyle of Lochalsh.

Uncertain why anyone needs a tutorial, or to do any math.. Illustrator has a built in tool for this sort of thing.

Grab the Polar Grid Tool (it's under the Line Tool). Hold down the Option/Alt key and click the artboard once.. enter your desired dimensions and divisions, hit OK. Done.
