if you need help, just give a shout.
i did the opposite of you for CAD/GIS. I got hired as a GIS Analyst and had to learn CAD. it was kind of a "shift" in my thinking, but a welcome one. i learned python scripting for ARcGIS --> now i'm starting to pick up LISP scripting for CAD. it's a wonderful world out there of programming languages!
btw - this is a great forum. kinda like the augi people, very knowledgeable and willing to lend a hand.
