I am trying to import an IGES file and am having trouble with feature recognition. The part was originally made in SolidWorks and then exported as an IGES file to be used in Ansys. I extracted the IGES file from the Ansys setup and do not have access to the original SLDPRT file. The only complex aspect of this part is the indents into the pipe. Does anyone know a rigorous method of identifying features when importing IGES files? I have attached the original IGES file and the SLDPRT file showing what features I have been able to recognize so far. Thanks in advance for the help!
