When you want to merge shapes in Photoshop, you’ll need to use the Merge Shape tool. This tool can be used to combine two or more shapes into a single object. You can also use this tool to merge shapes that are different sizes or have different colors. To merge shapes, first select one of the shapes and then click on the Merge Shape button. The Merge Shape dialog will appear. In this dialog, you’ll need to choose which shape you want to merge into the other shape. You can also choose whether you want the merged shape to be a copy or a new object. Once you’ve chosen which shape you want to merge into another shape, click on the OK button and then click on the OK button again when the Merge Shape dialog has finished displaying. The merged shape will now be displayed in your document as a new object.
