How can we draw a semi circle or half a circle in Photoshop CS3? WE can draw a complete circle by using the shape method or tool. If we want to crop the image to get a semi circle or half a circle, When we crop an image usually the image is cropped and resized in the background of the layer to form the whole layer. If we want to create a half circle, what will be the procedure. I am using Adobe Photoshop CS3.

    You can use the direct selection tool to mark an anchor point on a circle shape and then delete it thus making a half circle. Dec 12, 2018 at 13:07

Lazy method:

  • Draw the circle with the Ellipse tool
  • With the Direct Selection tool (A, the white arrow) select one of the anchors and delete.

Works great if all you want is a simple quick semicircle filled with color.

Drawback: it might cause trouble if you try to use stroke or other path operations (because it's an open shape). In which case I'd do it as Danielillo's answer.

    Or you could close the shape after, or make it a Custom Shape for that matter.

  • I tried but when I deleted one of the anchor points, the shape changed but not semi circle. I was not able to get the semi - circle by deleting anchor points. Dec 13, 2018 at 14:06
  • @PushkalSingh the shape changed to what? You have to use the Direct Selection tool, not the Path tool (shortcut P) otherwise you don't get the correct result.

  • Thanks. I was able to change the shape to semi-circle using the shortcut P. It worked to create the semi-circle. Dec 13, 2018 at 14:13
  • Draw a circle using the Ellipse Tool + Shift
  • Press Alt and use the Rectangle Tool to start drawing a rectangle shape from outside the circle until the center. Release Alt to make the rectangle from one corner to the next.

When drawing a shape on top of another, the Alt key subtract

    You don't need to hold the Alt key beyond pressing it and the mouse button at the same time.

    Using the same method with the marquee tools will produce a semicircle selection
