I have to make a graphic for a gauge. I want to draw a rectangle and array that rectangle in a circle at 6 degree intervals, so it makes a complete circle. Ive attached an image to show what I'm trying to replicte. I would normally do this in Illustrator but don't have access to Illustrator.

Can PS array with spacific degrees of seperation?

TIA

You can also duplicate the layer and transfer again. That will create layers that you can animate in a frame animation, So if you duplicate a rectangle layer and rotate it about a point 6 degrees 59 times you will have 60 layers you can animate like a sweep second hand in a frame animation. You could think of the 60 layer as a Group or an array of layers containing a second hand rotation position.

Photoshop Scripting model has object like documents, layer etc as arrays. You can process.

Sorry if i was unclear. I am trying to duplicate the clock face. All the white marks.

Use Text and Shape layers Rotate them merge some group some style them. All will be vector layers easy to edit and all will scale perfectly.

I wrote a Script you may find handy for something like this: "RotateLayerAbout.jsx"

Are you asking how to apply a radial gradient to a rectangular shape?

1. Draw a rectangle shape and give it any fill color.

2. Double-click the layer to bring up the Style Effects panel.

3. Add Gradient. Change gradient style to Angle and adjust values as desired. See screenshot.

thank you for your reply, but i attached an image when I orignally posted to clarify what I am trying to do. To answer your question, no, im not trying to create a gradient.

Photoshop does not have Construction Guides where you can type in 6° if that's what you are looking for.

When you use Free Transform, you can move the Pivot point, then type the degrees for rotation in the options bar. If the pivot point isn't showing, you can turn it on in Preferences. Put each rectangle on a new layer.

Thank you so much for the info! I used to be really good at photoshop...15 years ago LOL. I am so out of practice.
