Denny,

Thank you for the quick response. The propagation method in CAESAR makes sense and I am familiar with making modifications (globally) to a piping model through the List options.

Since this model was previously created in a separate program, every element (over 1000) was imported as a "manual" input. The Allowables list contains a "From Node" for each element in the model. So unfortunately, I think my only option is to manually change the piping code for each individual element.
