In summary, parametric design entails engineers’ piece-by-piece constructing a 3D geometry.

Users can record comprehensive design intent with features and limitations that make it possible to automate repetitive modifications using parametric modelling technology, on the other hand. Others, on the other hand, appreciate the level of control that comes with a parametric approach.įor many, the benefit of direct modelling is the ability to swiftly capture and record new geometry without the limits that come with parametric modelling. Since then, practically every prominent CAD tool, including SOLIDWORKS, Autodesk Inventor, Creo Parametric, CATIA, NX, and Onshape, has used the parametric paradigm.ĭirect modelling is the appropriate design method for some design engineers because of its openness and flexibility.

The 1987 debut of Pro/ENGINEER, now PTC Creo, marked a pivotal moment in the history of computer-aided design (CAD), since it introduced the CAD industry to history-based parametric modelling.
