Question

Slicing circle evenly

Asked by: brettr

I have two layers, each having a circle. One circle is smaller than the other and sits center.  I'd like to slice the circle evenly so that I can place icons into each slice.  The goal is to create a dial.  The center circle will hide each slice coming together.  I can use lines to create the slice affect.  However, that is very tedious and difficult work.  Is there another way to sort of automate the slicing so that if I want fewer or more slices, it isn't a big deal to do change the number of slices.  Any suggestions how that can be done?

I'm using Photoshop Elements 6 for Mac.

> I'm using Photoshop Elements 6 for Mac.

You're screwed.

I'm sorry. I just spent an hour and a half developing and testing a rather elegant tutorial on how to use the custom shape tool and typing in degree rotations to build a pie slice by slice in Photoshop. It's really quite nice actually.

Then I reread your question and saw that you were working with Elements. Drat!

Okay, all is not lost. I just don't get to show off my fancy tut.

Yeah, it would be nice if Elements or PS for that matter, had a dialogue box that let you enter the number of pie slices and it would take care of it for you, but it doesn't.

The best that I can offer is to use the Polygon tool. Type in the number of slices that you want. Then on a new layer, draw the polygon the size of your circle. The points will mark the exact place to put your lines, already divided up and spread out evenly.

If you hold down the shift key as you draw, the Polygon is constrained to being equal width and height as you drag. If you hold down the Option key as well, the Polygon will draw from the center (you did mark the center of the circle didn't you?) outward.

Not the perfect solution, but a whole lot better than trying to figure it out on your own.

Darn, it really was a nice tutorial too!

Best of luck to you.

That was excellent.  Thank you.  Couple of other questions below.

>>you did mark the center of the circle didn't you?
No - how do I do that?

I did shift and option to center the polygon but that just shows a dropper.  Am I doing something wrong?

The easiest way is to have the circle on a separate layer. When you do your transform thing, the control handles will come up in the exact center. Have your ruler open and guides turned on and drag a guide to the circle horizontally and then one vertically.

If the circle is not on its own layer, you can add a new layer and draw a temporary box around the circle and do the same thing.

I used to be mac/PD ambidextrous, but for the last few years I've been on a PC only. I called myself looking up the commands to reassure myself, but I could be wrong.

Check your manual under shortcuts. You should see the shortcuts for constraining a marquee or shape as you drag.
