dc.description.abstractIncreasing customer expectation on perceived quality for a premium passenger vehicle enables the automotive industry to focus on ensuring better fit & finish to deliver robust build vehicles. The development of verifying geometrical parameters on a vehicle in a virtual environment would save more time and money than working on a physical prototype. Finding such a virtual environment which allows to define and communicate the geometrical parameters is crucial for the automotive industry. Hence, the thesis was carried out in collaboration with Perceived Quality Geometry and Appearance group (PQ G&A) at Volvo Cars Group (VCG). This thesis aims to investigate the feasibility of defining geometric requirements for fit and finish such as gap and flush in 3D design environments of Computer-Aided Design (CAD) systems and/or visualization tools available within the Product Lifecycle Management (PLM) software. Also, the solution obtained should present the defined geometric requirements in the form of Portable Document Format (PDF document) and improve the accessibility of information flow between PQ G&A and the requirement receivers, also referred to stakeholders. Product development methodology was used to develop the solution for geometric requirements definition. Interviews were conducted with both PQ G&A and their stakeholders to understand the current working procedure of defining geometric requirements using a CAT software and their needs for a new solution. Also, software development experts were interviewed to understand the current and future development possibilities of the existing software available within VCG. Based on the result of the interview, four functional areas were identified and forty-seven product specifications were listed. Finally, four concepts which can fulfil the needs of PQ G&A in defining geometric requirements within 3D design modelling environment were identified and evaluated. The Catia V5 and 3D PDF add-on software were the proposed solution for defining geometric requirements. Today, this proposed solution partially fulfils the need of PQ G&A and require macro programming by the software development team to fulfil the complete list of the product specification. The proposed solution benefits in defining the geometric requirements within a 3D design environment and improves the accessibility of the information to its stakeholders. Yet, the efficiency of the solution can be evaluated only after completing the macro programming.sv
