The command objdisplay sets the model-level display status of objects (certain model types that can only be displayed or undisplayed as a whole). The command modeldisplay has the same effect but acts more broadly, on all types of models.
If the atom-spec is blank, all open objects will be affected. If an atom-spec is given, objects with model numbers corresponding to the specified atoms will be displayed. Otherwise, the argument(s) to objdisplay should be one or more model numbers or ranges of model numbers separated by commas. Note that a model_number is an integer and may be preceded by the # symbol (either with or without is acceptable).
Examples:
objdisplay 1- show the object associated with model number 1
objdisplay #1,5-8- show the objects associated with model numbers 1 and 5 through 8
~objdisplay :/isHelix- hide any objects sharing a model number with amino acid residues in helices
