Let me apologize ahead of time. I am a low end bottom of the totem pole tech support guy for the company I work for. One of our engineers received a great deal of IGES files that we cannot open. No matter the file I attempt to open , I get Unable to read Parasolid file. (58). Happens on all of the files.
Version of Femap is 11.3.2 Can anyone assist ?
What is the source of the IGES files? I've had a little experience with IGES files from Catia and you need to set the Customization radio button for Autocad on.
Try importing it into FreeCad (as the name suggest it is free) and if you succeed, you can export to STEP file, and usually that will work nicely with FEMAP.
