It is hard to tell without looking at your data file. However, here
is my best guess: maybe your file has long "bonds" that shouldn't be
there at all (maybe there should be TER lines in your file, or maybe
it has incorrect CONECT lines). When you show the surface it doesn't
enclose the lines because there are no atoms there. However, I can't
get this to happen in Chimera in my tests, so maybe your file is
incorrect in some way that makes it different from my missing segment
test case 1www (taken from the PDB, so it has correct format).
