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 /> <br /> == Links ==<br /> * [https://www.kubotek3d.com/blog/prt-the-legacy-3d-cad-format PRT: The Legacy 3D CAD Format]<br /> * [https://archive.org/details/usingcadkey00rese Using Cadkey book]</div>
