Can AutoPIPE import CIMSteel Integration Standards (CIS/2) or STP file information?
At this time, Dec 2022, AutoPIPE cannot import a STP file. However the proper workflow is to import / export CIMSteel Integration Standards (CIS/2) or STP file information with Bentley STAAD. After the model is in Bentley STAAD, then export the structure to AutoPIPE using PIPELINK.
