How do you rotate beams about their longitudinal axis 90-degree in RAM?
I totally agree with Jason. 100%.
That's really not a very good solution for RSS for a relatively mundane condition. Particularly since rotating a beam to have the strong axis horizontal is a pretty common way of configuring "wind beams" at intermediate levels and whatnot, where there is little to no gravity load but often substantial lateral loads from wind pressure on curtain walls, for instance. If that's a possible candidate for future development, I'd vote for that. I can keep checking wind beams in Enercalc, but it really seems like that shouldn't be a problem for a program that has an entire module devoted to lateral analysis. Just sayin'.

For RAM Elements you have the option to rotate:
