Sorry, the commands are self-documenting

The best way to find out what the parameters mean is to look at the tcl code that calls AC3D - mostly in the menu code in tcl/ac3dmenu.tcl.
If you can't work something out - let me know.
It's easy enough to make a script which pops up a window which say a list of button in it. Pressing the buttons can run one or more command. There may be some examples on here...
