Hello Meg,
Please see the “workarounds for surface failures” page — I suggest #3 in that page, using the command “molmap”:

… or using ChimeraX instead of Chimera to show the molecular surface, as it uses a more robust calculation method:

…ChimeraX “surface” command documentation:

I hope this helps,

I read through the forums and it seems that using the split command is the way to go, but I would not like to split this antibody. I'm trying to get a full rendition of the surface model of the antibody so that it is possible to 3D print the antibody. Can you please let me know if that would be possible? The pdb files of the 4 antibodies are attached.
