Why are the normal B31.1 Code Compliance combinations not appearing with the N-755-1 HDPE Code Comp combinations in the output report when using AutoPIPE?
All piping in the model are set to non-metallic or HDPE.
See Pipe Properties dialog:
When the HDPE Material box is enabled (checked ON), the material is classified as non-metallic or PE piping and only PE-.... combinations are applicable. Therefore, normal Code Compliance combinations do not apply and thus are not printed in the report for sections of non-metallic piping,
