Hi Shuhui,
There is no option to change the mesh line width in ChimeraX, sorry.
The grid density displayed when you first open the map depends on the data, i.e. if your map file grid has values 1 angstrom apart that is what the mesh will show (if you are also at step 1). You can change the step size in the Volume Viewer tool or with the "volume" command "step" option: https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#sampling
However, the "volume" command has options "subdivideSurface" and "subdivisionLevels" to draw more triangles in the mesh, as well as "squareMesh" to draw fewer lines: https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#dispsurf
For example, command:
volume #2 subdivide true subdivisionLevels 1
I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hello developers,
I have a question in using ChimeraX. May I ask how can I change the density of grids and line size of the mesh for a volume?
Best, Shuhui
