Problem:

The following is displayed when performing a model consistency check:

 W2164-63:  For following bend point(s) "the maximum dimension ratio (DR)   
     permitted for mitered elbow segments by CC N-755-1 is 13.5".               
     AutoPIPE will use B1, B2, and SIF factors based on DR of 13.5.

Why?

Solution: 

A simple warning notifying you of a code violation. The maximum dimension ratio (DR) permitted for mitered elbow segments by CC N-755-1 is 13.5. The program will default to using 13.5 regardless of your current modeling.

Avoidance:

Modify the model so the maximum dimension ratio (DR) used for mitered elbow segments pipe ID is below 13.5
