Via a FFI ("ForeignFunctionInterface") almost every lisp or scheme can communicate with AutoCAD. See http://xarch.tu-graz.ac.at/autocad/lisp/ffis.html

you must know more than just c++. you must know assembler also in the current
state.
and a lot of c.

obejctarx is the autodesk interface for the c++ world.
we don't need this, just the c++ functions from the various dll's.
or better the exported com objects, methods and functions.

no.

read the ffi doc and the bi4 and cormanlisp webpage.
good FFI's have acl, cormanlisp and lww.
COM support from a lisp only cormanlisp, acl and drscheme (mysterx)

> Can it use ObjectARX and produce an ARX ?

with acl you can produce dll's, loadable by others. I haven't tested it,
but a autolisp colleague of us plays with the latest acl version. for me it's
too expensive.

with cormanlisp you can produce a single arx plus a dll. but read my
cormanlisp webpage about it.
