The benefits of using feature-based CAD methodology and direct modelling are discussed inthe thesis. An experimental CAD study has been performed in which three different cases hasbeen modelled to get an overview of how direct modelling works in Solid Edge ST10 and to determine how the methodology could be integrated into product development. These two ways of modelling in Solid Edge are evaluated using previous research and data from thestudy to do a SWOT analysis and a Pugh matrix. Further on a comparison is made to find respective methodologies’ area of use.The experimental CAD study explores three cases in which each uses one type of product thatis investigated. The CAD models used as reference for the experiment are originally created using feature-based modelling, in the ordered module of Solid Edge. The intent is to recreate the models using direct modelling. The products of interest are created using different manufacturing processes which enables most tools in the Synchronous module to be put tothe test. Points of interests for the study is the workflow of direct modelling, to define the useand limits of Synchronous and investigate the synergy between the tools of the modules.It is concluded that direct modelling excels in certain area of operations where precision engineering can be ignored. When developing concepts for a new product, time could be savedby using the swift surface editing tool of direct modelling. When the CAD user does not need to rely on already set dimensions and is free to explore different shapes to create a 3D-model,direct modelling will come in handy due to its ability to model without taking history data into account. Direct modelling can also be used as a tool for creating redesigns of products containing complex feature trees. Cooperation between different CAD software could be strengthened using direct modelling where the need to redesign imported CAD files featuring “dead geometries” and empty history trees. These types of 3D-models, step, Parasolid’s etc can be easily modified using directmodelling in Solid Edge. Further research can be made to determine in which areas direct modeling can be applied and excel compared to the standard feature-based CAD methodology.

Von der ersten Idee bis zur Auslieferung eines Produktes laufen verschiedene Prozesse ab, die koordiniert und optimiert werden, um Produkte schnell zur Marktreife zu entwickeln. Die Digitalisierung von Prozessen sowie eine firmenweit einheitliche Datenplattform sind in der Produktentwicklung zwingend notwendig. Digitaler Zwilling, und PLM rücken in den Fokus. Die Herausforderung der Industrie liegt in der Optimierung von Produkten. Wo beginnt die Optimierung? Während der Konstruktion greifen verschiedene Optimierungstools in die Entwicklungsphase ein. Skalierbare FEM-Tools ermöglichen konstruktionsbegleitende Analysen. Verschiedene Konstruktions-Tools in der CAD-Lösung sparen Zeit und Kosten. Die Konstruktion der nächsten Generation Generative Konstruktion – bei der Modellerzeugung werden die Vorteile der additiven Fertigung einbezogen und somit die Bauteilkonstruktion optimiert. Reverse Engineering bietet die Möglichkeit direkt mit Facettendaten zu arbeiten und Flächen zu generieren. Convergent Modeling bietet die nahtlose Kombination von „B-Rep“-Volumen und „Facetten“-Modellen. Solid Edge Portfolio - die Zukunft der Produktentwicklung Solid Edge Apps erweitern den Funktionsumfang. Auf bestimmte Marktsegmente entwickelte Applikationen runden die Anwendungsmöglichkeiten ab.

Master’s thesis deal with commodities of metallurgical and connecting material in engineering firm. For these commodities is concocted an analysis of current statement, based on it will be designed its material standard. Purpose of this dissertation should be reaching of potential savings of money, time and increasing of productivity.
