Okay I think I found the correct file: C:\Program Files\PTC\Creo 3.0\M010\Common Files\text\config.pro
There were 4 with that name, but this one made the most sense.
It didn't have a set application to open it with so I went with Word. It gives this text:
drawing_setup_file $PRO_DIRECTORY\text\prodetail.dtl
format_setup_file $PRO_DIRECTORY\text\prodetail.dtl
pro_unit_length unit_inch
pro_unit_mass unit_pound
template_designasm $PRO_DIRECTORY\templates\inlbs_asm_design.asm
template_new_ecadasm $PRO_DIRECTORY\templates\inlbs_ecad_asm.asm
template_drawing $PRO_DIRECTORY\templates\c_drawing.drw
template_sheetmetalpart $PRO_DIRECTORY\templates\inlbs_part_sheetmetal.prt
template_solidpart $PRO_DIRECTORY\templates\inlbs_part_solid.prt
template_boardpart $PRO_DIRECTORY\templates\inlbs_ecad_board.prt
todays_date_note_format %Mmm-%dd-%yy
tolerance_standard ansi
weld_ui_standard ansi
search_path_file $CREO_COMMON_FILES\afx\parts\prolibrary\search.pro
I don't see anything about the graphic config option? If I have to add it to the file, what precisely am I adding?
Also, I tried opening it in Creo Parametric just to check, and it wouldn't do it.
It's a macbook pro running windows 7, AMD Radeon.
