Creo is a software suite which is developed by Parametric Technology Corporation (PTC) for supporting product design. Formerly Creo is known as Pro/ENGINEER.
Creo is a CAD/CAM/CAE featured 3D solid modeling software. It is used by mechanical engineers/designers for solid modeling, assembly modeling, finite element analysis, 2D orthographic viewing, sub-divisional and NURBS surfacing, direct and parametric modeling, and NC and tooling functionality.
Creo Elements/Parametric competes with other software like Solidworks, CATIA, and NX/Solid Edge.
Creo parametric is an upgraded version of Pro-E software which is useful for modeling, analysis and simulation. It is broadly used for product design & development in various automobile firms and manufacturing plants.
