Hi,
>> Is there any third party developer tool using which I can cutomize AutoCAD-LT using ObjectARX or AutoLISP?
As LT has no API .... you can't develop ARX or LISP applications, so also no developer can do that.
If your question is that there are applications out there that simulate LISP or ObjectARX on LT, than may be. I know one case of a LISP-interpreter that was running on top of LT (making it possible to run LISP-tools/applications on LT), in that case Autodesk was going to court with that company (that created that LISP-interpreter) as Autodesk sees that as against the license rules. My personal opinion: don't try that or at least ask a lawyer first, it's critical.
