Overview
Creo Elements/Pro (formerly Pro/ENGINEER), PTC's parametric, integrated 3D CAD/CAM/CAE
solution, is used by discrete manufacturers for mechanical engineering, design and
manufacturing. Pro/ENGINEER was the industry's first rule-based constraint (sometimes
called "parametric" or "variational") 3D CAD modeling system.[5] The parametric
modeling approach uses parameters, dimensions, features, and relationships to capture
intended product behavior and create a recipe which enables design automation and
the optimization of design and product development processes.
