    Blank file importing IGES from Maxsurf

    R. W.



      I'm trying to import this IGS file from Maxsurf modeller into SolidWorks, but all I get is an empty object tree and no mesh. I can import similar files without a problem, so is this maybe due to an error in the file (I've tried exporting it multiple times, with exactly the same settings as a working file). In the RPT file it is detecting the surfaces, but not converting them? There are no error messages, so I'm confused as to what to try next.


      Thanks in advance

            Hello R. W.,

            Yeah,.. that is or this is very odd..  the rpt shows the (2) rational b-spine surfaces but they are not processed?

            What I did, was open in Rhino3D and export again as IGES... again.. nothing... then, I saved as STEP,.. again,... nothing?

            ...lastly,.. I saved as Parasolid...  shazam!....but hmmm?.... I save/open and nothing... so,.. I save as a parasolid... "invalid data"...  wth?... last,.. I save as IGES...  FINALLY.. we have data!...  anyhow, here is the attached hull,.. image/file..

            ..things that make you go..... hmmmmmmmmm?
