[Chimera-users] "Cartoon" command unrecognized

[Dmitry Lyumkis]

Dear Chimera support, 
I am trying to display a protein as tubes, using the “cartoon” command. 
I am following some of the instructions here: 
https://www.cgl.ucsf.edu/chimerax/docs/user/commands/cartoon.html#style
However, I get “unrecognized command” when I enter “cartoon” on the command line. 
Could this be a version issue? My Chimera version is 1.15 (build 42258) 2020-12-18. 
Best, 
Dmitry
