Recently, I have been using ChimeraX for graphical analysis, and I find the software to be very user-friendly and efficient. I am currently facing a challenge where I want to display the van der Waals surface of a residue, similar to this illustration（https://doi.org/10.1038/s41467-022-31526-7）.

However, I am not quite sure how to write the command correctly. I have looked up the commands on the official website and tried using these two:surface #1:230； surface style mesh.

The bottom is open （the rad circle）, but I would like to have a complete van der Waals surface with closed openings, similar to what is typically seen in the literature. I would appreciate your assistance. Thank you！
