Engineered to Order (ETO) products can benefit from the concepts and tools offered by Product and Platforms Line Engineering (PLE) (such as increased variety offer and efficient use of resources), and CAD/PLM (Computer Aided Design/Product Life-cycle management) in order to gain competitiveness. This paper portrays a framework for describing and measuring the processes that conform that connection between PLE and CAD; presents a description of the key components of the entire process, their relationships, as well a set of metrics for assessing the ability of a process for creating Geometrical CAD Platforms. A case study of an ETO product development with the implementation of this framework is presented in two different scenarios for validating the concepts exposed and demonstrating the use of the framework for assessing the capability of an organization for creating 3DCAD platforms for ETO Products.
