Creo Parametric, formerly known, together with Creo Elements/Pro, as Pro/Engineer and Wildfire, is a solid modeling or CAD, CAM, CAE, and associative 3D modeling application, running on Microsoft Windows. Creo Parametric should not to be confused with Creo Elements/Direct Modeling, which was CoCreate ME10 (2D) and or ME30 (3D) CAD Products. The ex-CoCreate CAD Products are now owned by PTC and offered as "Creo Elements/Direct Drafting" and Creo Elements/Direct Modling". The software still cannot accommodate spaces in file names, even after more than 30 years of development.
