There are several ways of doing this, but an easy way is to turn Smart Guides on. View>>Show>>Smart Guides
Here’s some ways:
Straight lines from the corners will always intersect in the exact center.
In Photoshop, select the square and hit Ctrl-T. The Transform box will have a hub in the center of any object. Similarly, if you have the Move tool selected and check Bounding Box you will get the same thing.
The Transform and Bounding boxes go away when I select the Ellipse tool to create the circle.
Smart Guides seem to help, but it seems as though I can use those after the circle has been created? After I’ve created it, it seems to highlight the center with a pink dot. Before I’ve created the circle, however, they don’t seem to do much of anything..
Drag guides to the hub and you will always know where the center is.
Or put the circle on another layer and align them.
I only have CS, so no Smart Guides.
Way I do it is create both objects (on separate layers), Ctrl-click to select both, then align centres vertically and horizontally.
Haven’t bothered to explore Smart Guides so far – probably about time I did …….
that’s a nifty idea graeme!
How do you align centers vertically / horizontally?
When I Ctrl-click one layer and add another layer by Ctrl+Shift-clicking, I can move both selections around (although only one layer)… I don’t know how to align it, though?
Select the Move tool (V) – and the alignment and distribution buttons are in the options bar.
