bonds without atoms at the ends

Hello,

I am new to Marvin Sketch. I am trying to draw bonds without the carbon atoms or any other atoms at the ends of the bonds. For example, for  a single bond, i just want one line without any atom at the ends. For a double bond, just two parallel lines, without CH2 groups at the end. How can I draw this. 

Thanks

Hi,

On the Structure tab of the Edit > Preferences dialog, choose the "Never" radio button at the "Carbon Labels" section.

Best regards,
