Adobe Photoshop CS5 Extended Tip - Punch out holes in your extrusions!

When you have any of the 3D tools active, you can turn on 3D overlays from the bottom of the 3D panel to view the 3D Axis (the widget for manipulating meshes, lights, and cameras), light widgets, material and mesh bounding boxes, and a ground plane. Go to Photoshop (PC: Edit)>Preferences>3D to change overlay settings. To use the 3D Axis for meshes, lights, or cameras, select the right tool to invoke the 3D Axis for that property. For example, when you select one of the 3D Light tools in the 3D (Lights) panel and click on a light widget, the 3D Axis will now rotate and move the selected light.
