I just heard back from RISA tech support. RISA cannot model cold form steel walls the way it can wood framed walls. The good news is that it's in the works. )If anyone knows another program please let me know. As for now it's time to roll up my sleeves!
I’ve been using Simpson CFS designer. User interface is very simple and their newest update has like 10 different modules, including stacked walls, walls with openings, and shear walls. Only $500 for site wide license. While you can’t model full building structures, it pretty much has all the tools you need to design them, you will just have to piece everything together.
