When I export the file-types IGS, SAT, SLDPRT and STEP from an assembly containing configurations I'm getting a display anomaly. I've attached a picture showing the issue. Where the flange has interference with the main body of the assembly some material is disappearing. We've deliberately caused the assembly to have interference to represent the overall flange distance, taking into account weld contraction. Is it possible to export these files so that the material doesn't disappear and maintain the overall flange distance? Can anyone help please?
