RocketCAD and CAD packages

Does anyone know if RocketCAD runs within any CAD packages other than AutoCAD please? I see the documentation for IntelliCAD talks of support for
Lisp scripts which I presume would be key from the contents of the RocketCAD zip file, while I'm having trouble ascertaining if Lisp scripts would work in TurboCAD.
But the RocketCAD installation instructions talk of initial loading of a .arg profile and I'm not clear if IntelliCAD would know what to do with that.
And of course there may be other products I should contemplate.
I ask because I have inexpensive access to some CAD products but not to AutoCAD itself at present.
Thanks for any insights you may have.
