AutoLisp - Where to start?

Hi!
I am on the job learner and I have to develop couple of routines using Lisp.

Which is the best place to start for reading /practicing?

I will be using AutoCad4002 and 2004 for the programming environment.

Help appreciated!

 

Help -> Developer Help -> AutoLISP Developer's Guide

 

Start reading the newsgroup, look for topics with "Newbie" and follow the
threads. There are many new people the get a lot of help from the newsgroup.
Also, search google for "AutoLisp Tutorials", there are many out there! Type
VLIDE at the command prompt to take you to the Visual Lisp development
program to start programming and learning. Lastly, ask questions here. There
are no dumb questions, you just haven't learned the answer yet.

 

Forget about LISP, and start learning Visual C++ .NET

Because by the time you learn LISP, you'll have wanted to have learned a
higher language.

If you're young, and just starting out, trust me, you'll thank me for it
later.

Even though LISP is easy to learn and takes less time..?...you'll benefit
much more and gain higher grounds with mentioned above.

I agree with everyone else on the R2004 version but on the "other" version.
Maybe this site may be more help by then.

Not everything can be done by C++ within AutoCAD, so some knowledge of
AutoLISP is required.
Also, to jump into C++ is a huge learning experience plus cost of program.

 

Do you use .NET?

As for jump, he's about to make the plung.

He'd be better off learning .NET

As for cost, everything cost, especially when you're justing starting out.

It's better if he did it now.

The way I see it is no one is willing to commit to learning ObjectARX to the
MAX.

In his original post, Sam-Min mentioned that he needs "to develop a couple of routines". It seems that learning any variant of C++ is a bit of an overkill for his stated situation. Most people aren't willing to go to medical school just to learn CPR, and most AutoCAD customizers aren't willing to invest the time needed to learn and retain a higher programming language if all they need is the ability to automate or improve a few cad processes. Unless he's looking to build a career around his programming ability, chances are he's never going to get a return on his investment in learning C++. IMHO, part-time customizing of AutoCAD won't justify it. Unless, of course, he happens to be a programming nut like my younger brother and will use any excuse to learn yet another language. But that's another story...

 

wait a minute, how about we start learning it when you make the jump. I'm still waiting for you to hit some VB mr Tovar
<g>. I really recommend learning VB before c++ because you need to start thinking in the patterns of methods and
properties and classes before getting bogged down in making sure your string variables are dimensioned enough to hold
some string.
I do lots of VB and the fact is that lisp does certain things much better. I am wondering if using c++ will bridge the
disadvantages of VB. Having command line hookup is so valuable and VB kind of hacks it to pieces with sendcommands.

Don't cut out the most import parts...

Let's get down and dirty....

I just started with ObjectARX thats to ADN.

I like, and should have started the day it was introduced.

I cannot say what the best or quickest way of learning is but I can tell you
how I have learned. The nice thing about lisp is that it can easily do
very simple things which means that you can jump right in and do very basic
things immediately and then continue to build on it as your knowledge
increases. I still remember the first lisp routine I wrote. Back in 1990,
there was no mtext or automatic text editing so I made a simple one line
lisp routine that issued the change command and entered returns through the
default command line prompts until it got to the part where it prompted for
new text. It took all of half an hour to learn how to do that much and once
I accmplished that I was hooked. I did more and more complicated things -
all be self learning and one or two customization books.
