Recently, the development paradigm of enterprise information system has been moved from 2-tier environment to 3-tier environment. 3-tier environment makes possible to develop more efficient system in terms of the performance, extension, deployment and maintenance. The ship drawing process management system which manages a long-term drawing process and a great number of designers has to support an accuracy and a real-time of information but it is impossible because it is still served in 2-tier environment and some process of them is not developed yet. In this paper, we implemented the analysis and design of system based on CBD(Component Based Development) for the purpose of hanging the environment from two-dimensional Client/server architecture environment to COM＋ based 3-tier architecture environment. And by completing a development of total system, the productivity and the efficiency of the ship drawing process management system will be improved. And a wide reuse of components makes possible to improve the productivity and efficiency of system.

We present a real-time graph drawing tool for mathematics education. We developed a sketch-based graph drawing interface that recognizes the schematic sketch of a graph. Our system generates figures displaying useful supplementary information such as auxiliary lines, abscissas, and ordinates. The resulting graphs are very similar to the graphs commonly found in textbooks. We also developed a graph retrieval system that makes rapid graph drawing feasible.

DSME has successfully developed the unified CAD system (DACOS) for the commercial ship based on its design know-how accumulated for several years. Currently, DSME is expanding the unified CAD system to plant and special ship design. In this paper, the development of pipe design, especially, isometric drawing and BOM(Bill of Material) generation will be introduced isometric drawing and BOM generation are major activities of pipe design in shipbuilding. The drawing is used for pipe construction and installation while the BOM is used for purchasing and manufacturing pipe line. These activities are time-consuming and tedious jobs done by designers because the drawing should be generated as a non-scaled symbolized drawing that can be easily understood and the BOM information should be extracted without mistake. Therefore, we implemented automatic isometric drawing and 80M generation system for pipe design. In this paper, the developed system and the used technology will as well be introduced and a design output in a plant project as an applied example will be illustrated.

Recently, the needs for sharing and exchanging drawing information between 2D and 3D data in complex facilities are well recognized throughout the construction industries. The purpose of this study is to propose an information framework to represent 3D IFC (Industry Foundation Classes) -based drawing of building services in complex facilities as 2D drawing. In this study, 1) attributes of building service objects which are used in 3D CAD system are analyzed and present drawing standards are analyzed, 2) based on the analysis, an information framework is developed to represent 3D model in 2D representation, and 3) further more, to test a compatibility of the information sharing framework, number of standardized APIs and an IFC2Dbrowser are developed during the study.

In this thesis, founded on those considerings, plan the formula of media data for the information of drawing for the production of steel plate by establishing the concept of relational data model, plan the surroundings for query for the interface of user, and introduce the process materialized actually in detail as use the management system of drawing.

In Korea, the government has developed SEUMTER, an administration system for building related public service, to facilitate and promote the electronic submission and permission activities. SEUMTER is progressing legality system based on 2D drawing for building administration permission service. However, there are a lot of problems related to legality system owing to complexity of Korea regulation relation and structure, inefficiency of legality system based on 2D drawing, duplication examination of document (soliciting forms for civil affairs) and drawing. Therefore, the purpose of this study is to develop legality system for building administration permission service based on BIM in Korea. To achieve this purpose, the authors have investigated permission procedure and regulation structure that is used in current building administration permission and suggested permission procedure and regulation structure for legality system based on BIM. In addition, the authors have investigated element technologies (for examples, method of structured regulation, BIM model checker, Viewer, etc) for legality system based on BIM. Finally, the authors have suggested strategy and hereafter direction for application of legality system based on BIM.

For the implementation of CE(Concurrent Engineering), the TDMS(Technical Document Management System) which integrates design and manufacuring information, is required. In this paper a drawing information management system, one of the essential modules for the TDMS has been developed. The system is operated in SUN SPARC II workstations. A CAD software called CIMCAD-2D is used for the storage and management of drawings. Relational DBMS ORACLE is used for the development of information data bases concerned with drawings. As an integration tool, the multi-media software called LINKAGE is used. Various functions for drawings and concerned information have been developed with the internal language CIMSHELL and SQL $^*PLUS$.

A reward of the work which used physical computing in fields artistic modern installation is becoming large. But the example that used a robot cannot try to easily look it up on a tool of the drawing which isn't robot use for interaction. I will mention it about a user and a drawing system design and the developmental process which I can communicate with at these papers. I used a Mindstorm NXT system to have been said in Lego companies in the robot which composed working environment, and I classified it to virtual environments that I forecasted environmental actual drawing this, and I did simulate. I used an Icommand library to control a NXT system, and drawing used a processing library in actual environments for the purpose of in order to to express to virtual environment. I got image information, and I expressed to a vector method SVG file to bases for line drawing. This system can have already made it according to demand of a user as real-time communication is possible by bluetooth working together. These figures can work to one performance not being stopping to the results of already in processes doing drawing.

This study is concerned with the development of a project management system for the turnkey-based plant project, which will help the site manager to plan, control, and report the project progress. This system has been developed as one of the modules of the integrated information system for the H Heavy Industry Co. and is composed of five subsystems; project information system, drawing-material management system, process management system, project progress report system. A/S management system. it also integrates commercial project management package in order to schedule the project activities and report the project progress to the owner. The main purpose of the system is to provide project information, including drawing, material, and progress, to the site manger in the real time and to accumulate site know-how for the turnkey-based plant project.

GDS (Grating automatic Drawing System), which is an automatic design system of a metal product called grating, is a system that produces various detailed drawings on the basis of information within a Plan Drawing that represents layout of the grating such as locations, shapes, directions, etc. However, automatically produced drawings by GDS do not fully satisfy the standard of the general dimension marking method used among the layout designers. The lack of this standard quality mainly results from the fact that overlapping among dimension markings appear frequently. To solve the overlapping problem we applied the rule-based expert system. The rules are designed based on the expertise of skilled layout designers within the grating production lines.
