Spell Checker Dictionaries
The spell checker has two dictionaries, words and user_words, both stored in <modelcheck-loadpoint>/text/<language>/spell.
user_words—Standard dictionary. Add words from a Creo ModelCHECK report here. All Creo ModelCHECK users need read and write access to this file.
words—Default dictionary. Do not modify.
