Working with the Custom Shape Tool
Having the ability to draw a perfect polygon or rounded-corner rectangle is nice, however, Photoshop went way beyond standard shapes when it introduced the Custom Shape tool. Photoshop now comes packaged with dozens of pre-designed shapes, or you can even create your own. User-defined shapes can be literally any vector objects. For example, a company logo can be converted to a custom shape. Custom shapes have many timesaving applications. As previously mentioned, a company logo, if used frequently, is only a mouse click away. Any vector form, outline, or shape used on a recurring basis, can be converted to a custom shape and saved for future use. Select the Custom Shape tool or, if you have any shape drawing tool selected, click the Custom Shape button from the Options bar, and then configure the shape using the options on the Option bar.
