I have a few students that are learning vpython for science. They would like to be able to use a radio button to change what shape is displayed. However, I have been unable to see why the shape does not change normally (it overlaps) but that may be because I am horrible at editing other people's code. Anyone see the issue? Thank you! (yes I know they started with the widget example base but that was just to try coding this scenario).
