I see in the latest build of V4.3, there is a note that the restriction of a maximum of 20 load cases used in a combination case has been lifted.

I'm just curious, who's the one who needed more than 20 cases to define a combination case? I've never in my experience had 20 cases total for an analysis, much less trying to combine that many into a single combination case.

That must make for a helluva printout!

As of Version 4.30, you can have CAESAR II determine various Maximum/Minimum values from a <em>"set"</em> of load cases. This is where the limit of "20 load cases in a combination case" was encountered.
