There are two options in the IGES write settings area that will instruct TransMagic to create the most “benign” IGES file that typically all applications can handle well. The user should try checking the options “Write All Surfaces As Spline Surfaces” and “Write All Curves As Spline Curves”. This should create an IGES file that plays well with any application.
As always the best results are obtained by avoiding IGES altogether. TransMagic gives you the option to save a CAD Direct file like CATIA or CAD Kernel file like ACIS (*.sat) or Parasolid (*.x_t) which will insure the highest level of first time success.
