In the situation where there should be a gap between the design environments of 2D drawing and 3D BIM modeling, it is unavoidable aspect to face confusion caused by parallel usage of both technologies unless the project delivery systems are entirely upgraded to 3D. Therefore, it is critical to make efforts to minimize this confusion. Meanwhile, detailed drawings have very important roles in the construction process because they do not only concretely express construction methods for a given design plan but also provide basis for quantity takeoff and construction cost estimation etc. This paper suggests a plan to standardize detailed information based on BIM standard framework in order to make BIM realize the information. In the short term, this plan provides improved environment where both BIM and CAD technologies can be applied and, in the long term, it provides bases for BIM to replace CAD technology.

This study examines the significance of digital fabrication of scaled physical models in the digital design process and highlights the integration of design computing and digital fabrication in architectural education. Advances in CAD/CAM technologies have increasingly influenced building design and construction practices by allowing the production of complex forms that were once difficult to design and construct using traditional technologies. At the advent of digital architecture, schools of architecture introduced digital technologies to their curriculum, focusing more on design computing than digital fabrication, preventing students from completely mastering digital technologies. The significance of digital fabrication for scaled physical models as a design media within the digital design loop is discussed. Two case studies of leading schools of architecture that are successful in building the bridge between both areas are given. These focus on the curricular structure to integrate both areas within design studios. Finally, a curricular structure offering students a balanced approach to these areas of knowledge is proposed based on what was learned from these case studies.

A design process is difficult to describe comprehensively because a design problem has a multi-disciplinary nature and the design itself evolves as solutions are attempted by the designer. The process of design has been investigated in this paper with the purpose of characterizing the role that a system of this kind may have. In defining the system, an approach has been used that privileges the relationships with the existing CAD tools based on data exchange standards in course of definition today. Integrated design environment normally consists of a centralized data model a data management system and a set of CAD tools. In this study, all further investigations are directed towards the data management system, as one of the main components of the proposed environment. Moreover, product modeling, as a prerequisite for the data management core, is taken into special consideration.

This paper proposed to digital watermarking technique for architectural drawing using LINES and ARCs based on vertex in CAD system to prevent infringement of copyright from unlawfulness reproductions and distribution. After extract LINES and ARCs from designed drawing, we embed watermarks using adaptive algorithm in each characteristics. Watermarks robust to various attacks like as geometrical transformation as being embedded in LINE's length and ARC's angle information. Also, the proposed method satisfies enough transparency about watermarked drawing because have suitable embedding strength to each component. By experimental result, we confirmed robustness and invisibility of embedded watermarks in several conversions of architectural design drawing.

To propose the construction of architectural interior design and communication using graphic, web3D, it was studied the kind and character of various representation methods that can be embodied in an architectural interior design on the web, and looks into whether these ways can be adapted to an architectural interior design process. Especially, the use of the current techniques on graphic and CAD data give the most suitable effect by using the integrated data such as vector animation, an interaction of object VR(Virtual Reality), a high quality of panorama VR, and data treatment and its interaction of drawing of cad data. As a result, the single data format shows not only one image representation but also a stream of continuous operation through a change into another format. But this desired study expects that another next studies will go on interaction and integration of digital format with increase of transmission speed expected in the future, and a digital model and its practical methods.

Computers and internet have the potential to radically development. But, computer is a just tool by itself. This study is control implement in a way that exploits the capacity of network of processors to execute many tasks concurrently in architectural desigv. The collaboration design system constituted integrated CAD (computer-aided design) system at the base of standardization database environment network and world wide web (WWW). Collaboration design management system is composed of Project Management, Part Management, Process Management , and Appraisement system. They can provide frameworks for effective coordination and management of design work in accordance with the Collaboration Design Support System operating rule accommodatingly. architectural data can be collaboration design environment accessible through a web browser and located at a server. whenever their work investigated each others. Throughout process, the database acted as an individual design and it made them available in realtime. And they can have quick overview of the work. That way a continuous evaluation of best design was distinctly and highly. In the future, New architectural design methods are collaboration environment could result in productivity and quality.

기존의 소방대상시설물 도면은 이미지도면이나 CAD도면 형태의 2차원 도면형태로 존재하고 있다. 구축되어 있는 데이터의 형태도 다양한 방식으로 이루어져 있기 때문에 소방방재업무에서 필요로 하는 신속 정확한 대응체계를 위해서는 기존의 2차원 도면형태로 구축된 도면을 3차원으로 변환할 필요가 있다. 본 연구에서는 소방방재 대상이 되는 2차원 건축도면을 3차원 공간정보로 손쉽게 구축하기 위하여 건축도면에 대한 분석과 3차원 공간정보 데이터모델을 설계하고 이를 3차원 공간정보로 변환할 수 있는 툴을 개발하였다. 본 논문에서 제안한 소방대상 2차원 도면의 3차원 변환방법을 통하여 다량의 2차원 도면을 3차원 공간정보로 쉽게 변환할 수 있으며 이를 통해 소방방재 업무의 활용도를 향상 시킬 수 있다.

국내 BIM기술은 건축공사를 중심으로 적용되고 있으나, 최근 정부에서 인프라시설물 BIM적용 의무화를 검토하고 있으므로 토목공사까지 급속히 확대 적용될 것으로 예상된다. 인프라시설물은 광범위한 수평적 공간에서 공정이 진행되므로 BIM기술의 적용은 설계단계의 간섭관리보다는 시공단계의 공정관리 등 사업관리 전반에서 더욱 활용성을 갖게 된다. 4D CAD시스템은 시공단계의 공정관리에 적용되는 대표적인 BIM기술이나 실무적으로 활용할 수 있는 기능의 부족으로 실제 프로젝트에 적용되는 사례는 제한적이다. 본 연구에서는 상용화된 대표적인 4종류의 4D CAD시스템의 기능을 비교분석하여 프로젝트 특성별 선택 기준을 제공하고 실무적 활용성을 갖기 위해 개선되어야 할 기능을 분석하였다. 기능 분석결과로서 시스템별 장단점을 제시하였으며 시스템별 특성 분석으로 사용자의 활용 편리성을 제시하였다. 또한 토목시설물에 적용 가능한 기능 개선을 위하여 선형 4D시뮬레이션 방법론을 개발하여 인프라 시설물의 시공단계 BIM으로 활용성을 높일 수 있는 방안을 제시하였다. 철도 및 도로시설 공사에서 토공, 교량, 터널 등의 대부분 공정들은 수평적 공간에서 거리 축에 따라 작업이 진행된다. 따라서 단순히 기존 Gantt chart 방식의 4D 표현방법보다는 거리 축에 따라 공정이 표현되는 선형 4D 시뮬레이션 방법이 보다 실무적으로 도움이 될 수 있다.
