There are two purchasing options for cheetahSTC; the Perpetual or Leased option. The most popular is the Perpetual license; a once-off payment which provides an individual perpetual license, including all future updates of cheetahSTC. If you select the Leased option you will receive a full Perpetual license on the 4th lease payment.

Regardless of your purchasing option, after payment you will receive a USB security key. This will enable you to run the software on any machine. Please ensure you have Rhinoceros 3D installed on your computer.
