'''PRT''' is a format used by the CADKEY software from 1984 to 2004, during which time it was the most common variety of "PRT" file. A number of other programs also have different-format files under the [[PRT]] name, so things can get confusing. In 2004, CADKEY was replaced with KeyCreator, which uses the [[CKD]] format instead. KeyCreator can still read CADKEY PRT files, from version 5 and up.<br />
