Cannot create a Stress Isometric with a specific file.
After performing all other steps mentioned here, an isometric still cannot be created
Without reviewing the model in person or sending to the AutoPIPE development team, very hard to say exactly why a stress isometric is not generated. Try to round trip the model and then try to generate a isometric from a single selected segment of the round tripped file.
Reasons why stress Isometric was blank or does not create a drawing file?
