Kubotek KeyCreator is primarily utilized by professionals in mechanical or industrial engineering industries. It was first known as CADKEY Workshop, but CADKEY was then bought by Kubotek, which renamed the software to KeyCreator in 2003.

KeyCreator comes packaged with several pre-made templates. These CKT files are stored in the following directory:

\​Kubotek\​KeyCreatorPro[version]\​CKT\​

You can also create your own CKT templates that can be re-used to create CKD designs. To create a CKT file, select File → Save As..., then choose "KeyCreator Template Files (*.CKT)" from the "Save as type" dropdown menu.

You can only open a CKT file with Kubotek KeyCreator. To open a CKT file located in the default template directory, select File → New by Template. You can also open a CKT file by selecting File → Open..., then navigating to the location of the CKT file and selecting it.
