Good Afternoon,

I have a large piping model that was originally created in AutoPIPE (B31.3) but I am now using CAESAR and need to analyze this model according to B31.3 Chapter IX. I have no issues importing the piping model into CAESAR; however, the piping code under the allowable stresses tab is "greyed-out" as B31.3 for each individual element. Is there a way to change the piping code globally for this existing model or am I stuck with having to change the piping code for each element individually?
