Which AutoCAD product is best for design of projects that use steel extrusions? By extrusions I mean angle, channel, I-beam, rectangular tubing, etc. I want to design some utility trailers.
I realize I could use Architectural Desktop, which I have (2006) and I also have AutoCAD 2005, and get the tools for the extrusions as there already are some. In that case, where would you get the download that includes these tools? What's it called?
Here's Autodesk's product page:

I know I could research this myself, but I'm new to CAD and opinions from experienced users are helpful.
