Hello Francois, (There is a chimerax-users e-mail list, CC’d here.)
Note that the surface displayed in Chimera and ChimeraX is the SES, not the SAS. For spacing of points, see the “surface” command option “gridSpacing” — use ChimeraX command “help surface” or view the help at our website: http://rbvi.ucsf.edu/chimerax/docs/user/commands/surface.html#options
Use ChimeraX command “save formats” to see what formats you can save. STL or X3D would include the surface vertices, I believe. For full details on “save” use command “help save” or see the copy here: http://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html
I hope this helps, Elaine ---------- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hello, I am not interested by surface normals, the 3D coordinates would be enough.
Is it possible to control the surface sampling of the surfacing algorithm? Like with a number of points per Angstrom^2 parameter? Thanks a lot, Francois.
