methods to open IGES/STEP format with PROE-4
The problem could simply be due to dots and dashes,
ie. file named "part-model.stp" will not load
change file name to: "part_model.stp"
and try again.
hi, may be the part name having the space. ex: part model.stp or part model.igs.
Remove the space, and try it.
