KeyCreator is a non-parametric, non-history based, "direct" 2D/3D solid modeling CAD program.

Originally known as CADKEY,[2] it was first released in 1984, running on DOS, UNIX and Microsoft Windows operating systems.

KeyCreator is available for English, German, French, Italian, Spanish, Japanese, and Brazilian Portuguese.

Aero Tec Laboratories used KeyCreator to design crash resistant, nonexploding fuel-bladder tanks for aircraft, race cars, and performance boats.

They have made custom bladder tanks for NASCAR, Ferrari, Boeing, Lockheed, NASA and the U.S.
