Yes that would be good (reference Enhancement #120330)

We did enhance the user defined wind loads to support wind tunnel results in 15.04, but it's not quite the same as user defined pressures.

That's what I was expecting, thanks Seth. In the future, will RAM ever provide the option to manually enter wind pressures in modeler? I think this would be an incredibly effect, time saving tool.

Our program generated wind loads always assume a like amount of windward and leeward exposure on each rigid diaphragm. For cases where that's not true I recommend User Defined Wind Loads for accuracy. https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/2052/ram-frame-wind-loads-faq

For semi-rigid diaphragms you can adjust the percentage on the windward vs. leeward edges with each user defined wind load case.
