How to cut a circle in half in Photoshop as well as in Affinity Photo, how to create two halves of a vector circle in seconds and then re-color the design.


1. In Affinity Photo

Go to the circle and then convert the design to a curve. You will then have nodes to work with. Go to the node tool and select the top node and then go to the action along the control bar (top of the screen) and clicjk the break curve. Select the bottom node and repeat the same action. Go to the move tool and select one of the two curves in tghe layers panel and drag away. You still need to close the curves, go to the actions and for each of those curves, click close curve. You can re-color the design, add layer effects etc

2. In Photoshop

There is no break curve etc in Photoshop, so a workaround is required. Create a rectangle shape (use vector shapes) and create it bigger than the circle and then place it over one half of the circle, you can use smart guides via the view menu to make it easier. Select both of the shapes, the circle and rectangle and then go to the layer menu and combine shapes and subtract command and now select all the points in this 'combo' by using the direct selection tool and then goto the control bar and set operations and select the merge components option. Now select the semi-circle and duplicate it using the alt / option or layer duplicte and then rotate it 180 degrees and change the color of one of the halves (or not)
