[Chimera-users] Remove shapes programmatically

Hello. I'm having a problem working with shapes in chimera. I'm adding shapes with a script using commands like: shape tube #:1@CA#:100@CA radius 0.1 I want to remove some of the shapes later in the script, however i can not find the proper way to do it. I know is posible to do it using the GUI (picking the shape with control key and then "Actions>Surfce>Hide" in the menu bar), but i dont know how to do the same with the command line. Also, i can not find the way to manipulate existing shapes (increase radius, change color, etc). There is a way to delele, hide or manipualte shapes? Thank you all.
