Pre Engineered Metal Building

[Evolution]

Of late, I'm doing more commercial buildings from scratch using PEMB structure for the frame.  I've seen over the last year several post dealing with designs using pre engineered metal building structures.  I did a quick look but didn't find those threads. I thought at one point one of our great CA user guru's had done a wall design using the metal building structure, does anyone remember that. I'm sure I saw some details showing the typical metal building framing, or did I? I'd like to create the wall type that looks as realistic as possible and I know I can probably do 3D molding poly lines, or poly line solids to create some of the detail for the sections I need but, if someone had already done it? 

Thanks!
