Dear Lorenz, If I understand correctly, you do not need to convert the sphere surface to a volume. The "volume mask" command uses a surface model to delineate the masking area of your map, see: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/volume.html#mask> I hope this helps, Elaine ----- Elaine C.

Dear chimerax-team,
I am looking into a possibility to generate a spherical volume in chimerax that I can then use as a spherical mask for focused 3D classifications and signal subtractions. For my specific need, a sphere would be the ideal shape. So far I managed to generate a surface model using the ‘shape sphere’ command, to place it to the region of interest and resampling it onto the coordinate system of my protein of interest. Is there any possibility to transform the surface model into a (binarized) volume?
Best, Lorenz
