Stress isometric drawing are blank or not created, why?
Answer: Not using AutoPIPE Advance or Nuclear licensed edition.
AutoPIPE V8i 09.06.02.xx and higher has the Stress Isometric feature incorporated into the application and does not require any additional licenses. However, one must enable AutoPIPE Advance or AutoPIPE Nuclear Edition under the Configuration command (File > License > Configuration) in order to generate a Stress Isometric.
