In this series of tutorials, we'll learn how to enhance a hand drawing to become an astonishing final render of a technical cross section. We'll begin by drafting the technical cross section drawing in AutoCAD based off of a rough hand sketch. Once the cross section is finished, we'll then import the drawing into Photoshop to add textures, light effects and people. By the end of this tutorial, you'll understand how to take advantage of these processes used in Photoshop to transform your hand drawings into final renders that will amaze. Software required: Photoshop CS4, AutoCAD 2013.
