NEUTRAL special format for transfer models in old versions PRO/E, 5 ->4->3 ...
look like to .stp or .igs
commands not save, only geometry

simply the file is in other format like STEP,IGS etc. this file cannot shows the features like extrude,hole,etc... it can't be edit.
but there is an option called FEATURE RECOGNATION.
these can be available in PTC web site. check it.
