5 Preface The research described in this thesis has been performed at the Computer Graphics and CAD/CAM group, of the Faculty of Information Technology and Systems of Delft University of Technology. Supported by my promotors, Erik Jansen and Wim Bronsvoort, I continued the research on feature modelling that has been going on in the group for several years now, and focused on multiple-view feature modelling to support conceptual and assembly design. Parts of this research have been previously published in (Noort and Bronsvoort 1999; Noort and Bronsvoort 2000; Noort et al. 2000; Noort et al. 2001; Bronsvoort et al. 2001; Noort and Bronsvoort 2001a; Noort and Bronsvoort 2001b; Bronsvoort et al. 2002; Noort et al. 2002). Many people of the Computer Graphics & CAD/CAM group supported me in a variety of ways. I wish to thank them all. In particular, I would like to mention the people of the feature modelling project. Wim Bronsvoort, my supervisor, trained me to be a conscientious researcher; his suggestions and comments have been a valuable source of inspiration for me. I enjoyed to work with him, especially the many discussions we had, and hope to be able to continue the co-operation in some meaningful way. Rafael Bidarra, my roommate and fellow researcher, provided a valuable source of feedback on various topics. His presence has broadened my view and his perseverance has been an example for me. Ruud de Jong, the technical assistant of the project, also helped to asses the significance of new concepts with his critical remarks. Without his support, the current prototype modelling system would not have been possible. Eelco van der Berg, who joined the project as a graduate student and continued as a PhD student on feature validation for freeform features, has been a nice and valuable colleague. Further, I would like to thank the graduate students who have contributed to my PhD research project. Geoffry Hoek has done a very good job in creating a GUI to integrate part and assembly design. Never satisfied with his own work, he kept refining it, resulting in a long but very valuable project. v

6 vi Preface Jeroen van der Berg has worked on a GUI to integrate conceptual design with part and assembly design. His dedication to his graduation project was unprecedented, and resulted in an important contribution to my research project. I would also like to thank the members of my committee, in particular Prof. dr. I. Horváth, for the attention they paid to my thesis. Finally, I would like to thank my parents, Jan and Joke, and my brother, Gerard, for their invaluable support. Alex Noort Delft, July 2002
