I am designing the connections using RAM connections. When I switch from RAM structural to RAM connections I am seeing the warning " The analyzed load cases have changed and load combinations should be regenerated".
However, under add/edit, there are combinations already generated C1, C2, C3, etc...
But because of the warning I generated the load combinations again and these new load combinations are added as D1, D2, D3 ...... etc.
What is the difference between load combinations called as 'C' & 'D'? and is it necessary to generate load combinations again because of the warning.?
Also, connections are analyzed for both C & D combinations in the report.
The combos that come in from RAM SS are noted as C1... The C prefix is used regardless of the type so that the combination numbers all match up with the original coming from RAM SS.
The combos generated with Ram Connection templates have different prefixes based on the Type of combo (S for service, D for design, AS for amplified seismic, C for unspecified). Regardless, the Combo ID prefix is of no consequence since the last field for "Type" is what actually matters.

Seth, just wanted to clarify...does this mean he did not need to regenerate the load combinations because of the warning? If he had not, would it still work? And if he didn't, the combos used would not follow the RAM Connection template with the different prefixes for service and design as you mentioned?
