The marquee tool can make selections that are single row, single column, rectangular and elliptical. Photoshop's non-destructive Smart Objects can also import complex vector shapes. To create very complex vector graphics with numerous shapes and colors, it may be easier to use software that was created primarily for that purpose, such as Adobe Illustratoror CorelDRAW. These tools and commands are convenient to combine pixel-based and vector-based images in one Photoshop document, because it may not be necessary to use more than one program.
