There are books and other resources you can find by searching the web, but before you even think about ObjectARX, you have to start with C++, because that's the programming langauge it uses.
I'd estimate that it requires 1-2 years before the average person that has never used C++ is able to develop ObjectARX applications in C++.
You may be better off hiring an experienced developer, or at least, make sure your fully understand the time and expense of learning (and the cost of learning mistakes), and convey that to your company's management before they make a decision. I say that because if you ask me, you have absolutely no idea what you're getting yourself (and your company) into.

Hi all, We're looking at purchasing a AutoCad add on program for creating factory design drawings. The program comes with ARX and XML objects. We'd like to beable to create our own components (conveyor systems, clay extruders ect.) I've been doing some reading online over the last day and ahalf and it looks like ObjectARX would be the best alternative. I've done some Lisp programming and have used AutoCad for 16 years. I'm hoping someone can recommend a entry level book, web site ect. to get me started, this is all new to me. We're using AutoCad 2008 with windows XP. Thank you, Joe Andreasen Keyria Inc. Littleton CO
