PTC Creo Parametric
Known previously as Pro/Engineer, it is the first software to use the parametric model based on features. This modelling type involves a sequence of processes for adding or removing volumes (i.e. features) on the basis of profiles that rest on planes. The parametrization of the dimensions allows for the faster modifications of the feature geometry and the setting of constraints and formulas to automatize specific procedures. It can be easily customized and integrated by additional packages dedicated to specific functions.
