The drinking glass assignment requires that you take a screen shot of your revolve curves. Here’s how to do this:
Windows and mac:
Make sure the viewport you want to capture is active, then run the command – ViewCaptureToFile.
the Mac OS has an easy to use screen capture tool built in. Press Shift+Command+4 and a cursor will appear that allows you drag an area to capture as a screen shot. You should hear a shutter sound, this means that the image is saved to your desktop.
Windows has a built in app called “Snipping Tool” that can be used for screen shots.
