Double-click on desktop "Pivot" icon.
Open the "File" menu and click on "Load Figure Type." Highlight the figure you wish to edit and press "OK".

Click on the "Line" tool. Place your cursor over the red dot at the bottom of the arm. Press the left-button of the mouse and drag the mouse toward the side of the window. Release the mouse button when the line looks like the short handle of a gun.
Adjust the width of the line, if necessary. Press the "Up" or "Down" button to increase or decrease the thickness. Typically, the line of a gun is slightly thinner than the width of the arm.
Connect the first line of the gun to the gun's barrel. Draw a long, thin line using the "Line" tool.

Add only the gun to the animation, if desired. Click on the red dot at the edge of the figure and press the "Delete" button. Delete all of the lines, from the outside to the inside, until only to gun remains. Open the "File" menu and scroll to "Add to Animation." Enter a name in the pop-up window and press "OK."
