Creo is a family of Computer-aided design (CAD) apps supporting product design for discrete manufacturers developed by PTC.

Creo runs on Microsoft Windows and provides software for 3D CAD parametric feature solid modeling, 3D direct modeling, 2D orthographic views, Finite Element Analysis and simulation, schematic design, technical illustrations, and viewing and visualization.

Creo can also be paired with the Mastercam machining based software.

PTC began developing Creo in 2009, and announced it using the code name Project Lightning at PlanetPTC Live, in Las Vegas, in June 2010.

The Creo suite of apps replace and supersede PTC’s products formerly known as Pro/ENGINEER, CoCreate, and ProductView.
