[chimerax-users] Adjusting sphere radius

I’ve issued the following commands for my models select <help:user/commands/select.html> #2/A:120,119,41,36,37,34,49,117 72 atoms, 68 bonds, 8 residues, 1 model selected setattr <help:user/commands/setattr.html> m ballScale 0.2 create true Assigning ballScale attribute to 2 items No changes were observed on the ball scale. Is it likely that I should be trying something different to change the ball diameter? Thank you
