You don't HAVE to use AutoLISP. If you know C/C++ then I would just learn
the AutoCAD ARX functions. If you know or want to learn VB, Since R14
AutoCAD has VBA in it.

So you have AutoLISP (and Visual LISP in A2K)
ADS/ARX
VBA

With all due respect -
It looks like there may be other problems, other than, which programming
language you are wanting to use!

As I know Autocat is NOT writtten with LISP, why have to use LISP as the
customerized language?

why not C++ or something else?

ITs already a fact It'd used LIST, then how do I get started with LISP?
I never learnt it, I knew Pascal and C only.

Well, AutoCAD is one of the few programs around that _does_ let you write
customization programs in the same language in which the program itself is
written. There is no inherent reason why you _should_ write customization
programs in the same language as the main program ... but you can write
extremely powerful programs in C++ for AutoCAD, and you can do some things
you can't do in LISP or VBA.

LISP is a pretty good choice for AutoCAD customization. It's very good at
processing the kind of data that is used by CAD programs.

AutoLISP is not particularly great at interfacing with other programs or
using object-oriented programming, but it's improving.

LISP is a lot cheaper (once you've bought AutoCAD!) than C++. Most people
find it easier to learn the basics of LISP than C++, starting from knowing
nothing. LISP feedback is typically faster than the C++
write-compile-link-run-crash-repeat cycle. And it's difficult or
impossible to blow away your program, data, or system from LISP. You can
make some _really_ dangerous mistakes in C++!

As for how you learn it, write some short and simple programs. Then get
some programs from these newsgroups or from the web that do almost the
same thing, and see how differently they were written. Figure out why. I
know that those first few steps seem impossible, but if you start you'll
get to the end.

There are several good books on AutoLISP, some of them a little out of
date. "AutoLISP in Plain English" is highly regarded.

My two cents worth:
AutoCAD does not compile C++. You can write C++ to your hearts content but
when you want to compile it, you need a C++ compiler. The cost of such a
compiler is not included with AutoCAD. AutoCAD interprets uncompiled LISP.
And does so almost instantly with today's processor speeds. And it's
included! No need to run out and buy a program to read and compile your
code. It just isn't necessary. That's why LISP is still the favorite
AutoCAD tool. Even if you can't do as much as you can in C++. You can do
almost everything, and for free, that's a real bargain.

You know nothing about the power and style that comes with C++, the price to
gain that is not that much. Frankly speaking, VC++ in technique is far more
worth money than AutoCAD itself. the market is different and that makes
AutoCAD more expensive. If you could pay for AutoCAD, the price of VC++ is
negligible.
If you are really building a professional application that uses AutoCAD as a
CAD space, then you must move to C++. if you are for small tools that help
your drafting you can use AutoLisp, the best is if you know how to combine
both.

You have just pointed out the biggest advantages and the biggest problems
with AutoCAD today. Just as you said, if you want simple drafting tools,
LISP is a great bargain. AutoCAD started out as a drafting program, now
Autodesk wants it to be everything for everybody. That is why it has become
the over-coded, bloatware monster it is today. You get what you pay for,
and with AutoCAD today, the average user pays for much more than they will
ever use.

This is true with most programs. Most users use about 20% of the code in the
program. With 34 gig HD's making their presence in common machines, bloated
programs are hardly the issue anymore.

LISP is a great way to customize AutoCAD and C++ is the best way to write
"programs" but it seems VBA has been left out here. This programming
environment is also free with CAD.

I for one am sort of afraid to write code anymore, I keep having to go back
and change it due to AutoCAD "upgrades" and am tired of feeling like a rat

This is the most commonly spread misconception, IMHO,
when you think of Lisp as some kind of a "macro"
language.

Lisp is a great bargain for just about anything. You
only need to implement in C++/VB those parts that
can't be done from LISP (mainly, some esoteric interfaces
like modeless dialogs with tree controls, and number
crunching routines), but the whole system is best
to be written and maintained in Lisp.

Finally & finally, I found the way to combine Delphi and aCad with activeX.

Thanks Tony! May I have your email or ICQ#?
