Drawing in the View: To draw in a View, choose a View and tap the Draw icon in the menu at the bottom of the screen. A window will appear showing drawing tools. Use "Marker" to draw over anatomy in the View. Selecting "Eraser" allows you to erase your markings using your fingertips, while "Erase All" clears all markings from the View. You can also choose to "Email" your View with your drawing, or "Save" your drawing to the Photos folder on your iPad.
Exit the draw mode by choosing the "Done" button in the upper right corner of the Draw window. If you exit the draw mode, your drawing will be erased, so be sure to save or email your drawing first if you wish to preserve it for future reference.
Taking a screenshot: To take a screenshot while in a View, tap the Screenshot icon in the menu at the bottom of the screen. You will have the option to choose "Email" or "Save." If you choose "Email," you will be prompted to enter an address and title for your message. Saving the screenshot moves it to the Photos folder on your device.
