Dear ChimeraX team,

I want to select only the sidechains of a protein in order to visually outline them for a figure. This isn't an issue if cartoons are turned off, because I can select the only sidechains I want and use the command:

`sel sel & sidechain`
and I outline them in a nice way with...

`graphics sel col black width 2`

However, if cartoons are turned on then this won't select just the sidechain, but select a portion of the cartoon backbone too. I'm not sure how to specify this.

Ideally I want a transparent cartoon with opaque sidechains, and then have only the sidechains selected. Please see the images attached for examples of what I'm referring to.

Many thanks,

James
