Advantage of OBJECT ARX Programming

Anonymous — Thu, 09 Aug 2007 07:14:50 GMT

Hi,

Can anyone tell me about the advantages and extra features of OBJECT ARX programming?
Since we already have VBA,VB and AutoLisp tools as the best customization tools for autocad, why it is necessary for anyone to go for OBJECT ARX
Please give me a listing of extra features in OBJECT ARX programming which does not available and cannot be done using autolisp and VB.
My first preference would be always AutoLisp as there is no portablity problem from any previous version to latest versions.

Sri,

If you are starting a brand new project and donot have any legacy issues
like we do, it is best to start with c# and vb.net using Dot Net. I would
recommend Object ARX /c++ only to maintain existing applications

I cannot answer your question directly because I dont great knowledge on
Lisp or VBA.

For our situation AutoCAD is just one component of our software. So to get
a unified feel we get to use c# for AutoCAD, ASP.Net and Webservices. So
there is no new tool training.

Going back to answer your question AutoLisp is just bunch of script based
language, you will not get the control and power of c#.

Jay Balapa....

>I would recommend Object ARX /c++ only to maintain existing applications

Why?

Talking from someone that came from autolisp/vlisp for so many years, and
have spent more than 3 years in C++, ARX, MFC.... and being learning C# -
but prefer the hard way as many will think C++ or ARX or MFC can be....

Thanks!

The only one thing that is not possible in other Customisation tools is the
possibility to create your own Custom Entitis. For now at least.
There is naturaly an big advantage of C++ over others programming
languages - speed. If you compare AutoLisp, VBA and native c++ you will see
that.
On the other hand there is an disadvatage too - there is any 2-3 versions an
binary compatibility break. So you have to maintain your code a very
"special" way ;].

Naturaly there is allways the possibility that in the future on RXXXX
version you will see - Autolisp is no more supported (included but no more
supported).

Hope that helps

Rex
