    Hi Bingchun,
    The "combine" command is only in the daily build.  It was added after release 1.2.  

    No idea what you mean by only partial files saved.  The "save" command or menu File... Save will save all of the atoms if you don't use the "displayed only" or "selected only" options.  If not, you could use Help... Report a Bug and attach your session and say exactly what save options you used on that session and why you think part of the result is missing.

    Just use the "save" command or menu File... Save and choose PDB format and one of your atomic models, and make sure to use the option to save "relative to" the map model.  You could do that twice to get two new PDB files

    see
    <https://rbvi.ucsf.edu/chimerax/docs/user/commands/save.html#pdb>

    If you wanted both of your original atomic models in only one PDB file, it may be best to combine them into a single model first.  E.g. use the command  "combine" (requires recent daily build, is not in version 1.2) on the two pdb models to make a new combined model. For example, combine models #2,3 to make a new model #5:

    combine #2,3 modelId #5 name mynewmodel

    see
    <https://rbvi.ucsf.edu/chimerax/docs/user/commands/combine.html>

    ...then use either the "save" command or menu File... Save as above to save the new model relative to the map.

    I hope this helps,
    Elaine
