    ABSTRACT In this paper we propose a method to generate 2D drawinglike views from 3D models automatically. The view generation process is conducted in object space and supported by two algorithms: (1) pose determination for 3D models: unifying the space between 2D drawings and 3D models; and (2) 2D drawing-like view generation from 3D models: building the correspondence between 2D drawings and 3D models. The pose determination method for 3D objects is proposed on the basis of a concept called Virtual Contact Area. Meanwhile an efficient occlusion algorithm based regular grid is described to generate orthogonal drawing-like views from 3D models along the pose orientations. To evaluate the validity of the proposed methods, respective experiments are presented. INTRODUCTION As two different ways to express and communicate design ideas, 2D drawings and 3D models are now being widely used in many fields. For designers with special skills, 2D drawings are usually used as the principal way to express ideas; while for most common users, 3D models are more intuitive than 2D drawings from the perspective of information communication. How to seamlessly transit between the two representations is a public problem for many researchers in engineering fields. In spite of the fact that many methods To find the optimal orientations for a 3D model, Park et al. [4] used a pose determination technique to integrate tw

    This dissertation presents an enterprise modeling approach to support the efficiency and dynamic nature of the ship early design phase. The modeling approach is based on the principle concept of the integration between data and process. This concept is applied by taking into consideration the specifications of the early design stage. Therefore, an information model as well as a process model for the ship in the early design stage are developed. Thereby, predefined activity as well as configuration concepts are applied to represent the early design process and support its integrated nature
