3ds MAX Commands

MAXScript allows you to invoke 3ds Max menu and toolbar commands from within scripts using the max construct.

The general syntax for max commands is:

max <command_name>

EXAMPLE:

max file open
max unhide all
max hold
max time play

The keyword max is followed by one or more words that describe the command. The available commands can be displayed using the '?' character in a partial max command:

max time ? -- show all the time-related commands
max sel ? -- show all the commands with 'sel' in them as a substring
max ? -- show all the commands (there are a lot!)

The max command always returns the system value ok .

NOTE:The max spacebar max command appears to do nothing when invoked from the Listener window, because the spacebar command is window-specific and only locks selections in the active window. Because it is the Listener window that is active, 3ds Max effectively ignores this command.
