The zone command makes ribbons thinner outside the zone by default and it was not making the arrows smaller.

I have fixed it in tonight's ChimeraX builds.

Hi Meinan,
It looks like the cartoon style “arrowScale” factor was changed to a large value, maybe by an accidental command?  You could try this command to put it back to the default value:

cartoon style arrowScale 2

I hope this helps,
Elaine

Dear Dr.,

The attached is a picture I saved which the stands' arrows are so wide when using chimeraX to draw some figures, could you please tell me how to make it normal?
The problem showed after I put into these two command(not quite sure yet):1. zone #3:Lig residueDistance 5 label false  2. cartoon #3/b suppressBackboneDisplay true.
Thank you very much!

Best regards,
