Sometimes , we get something else in our minds and we want to change or delete the shapes from the document. Now, as we have added the same Shape Layer to both of the shapes, it will be difficult to change or remove it. The whole document will get messed up. The reason behind this is that both the shapes are existing in the same layer. But, in Photoshop, we get the option to change or delete a shape.
We can also switch between the modes of selection. Like, if we want to change Subtraction mode into Addition mode, we can also do this. Go to the Path selection tool and click on the arrow. Now select the second shape and click on the mode you want to add from the option bar.
If you want to entirely delete a shape that is added to the existing one, it can also be possible with the Path Selection Tool. select the shape as we did before and press Backspace from your keyboard. The selected shape will be deleted easily without deleting the whole shape.
Hence, this is the whole process we need to follow to combine shapes in Photoshop. Circles, squares, rectangles, triangles, and many more shapes are combined together to form a new shape. Then, some of their parts are added, subtracted, intersected, or excluded to have more interesting shapes. Today, it is not a big deal to play with shapes and combine them.
