This paper describes a solid modeling system based on a systematic description of techniques for analyzing and understanding on engineering drawings. Main stress is placed on clarifying the difference between the drawing understanding and the drawing recognition. The former, in which we feel major interest, is intrinsically a difficult problem because it inherent contains combinatorial search to require more than polynomial time. Actually, understanding drawings is regarded as a process to recover the information lost in projection 3-D objects to 2-D drawings. But, solid modeling by automatic understanding of the given drawings is one of the promising approach, which is described precisely in the text. Reviewing the studies performed so far, we summarize the future direction of the project and inevitable open problems left.

This study investigates great potential of architectural representation drawings for architects as well as designers to realize their design concept into visual forms. In 1988, an exhibition called "Deconstruction in Architecture" at Modern Art Museum, New York, was an important turning point in design representation. The study examines design drawings of architects of deconstructivism to analyze new attitudes toward building forms and programs in contemporary architecture. The study found in the drawings that initially, collages in many different types are often utilized to express simultaneous time and space. Secondly, section drawings become more important to explain ambiguous and complex floor system than before. Thirdly, cinematic montages are utilized to express indeterminate or loose programs. Fourthly, diagrams are utilized to visualize initial conditions and clues of design solution. The study concludes that design drawings are not only representation media admitting of changes and progress but also tools of design creation. creation.

These days, interior construction is performed to prevent the deterioration of old building finishings or to make distinctive designs. In case of interior construction, a construction cost is estimated through basic 2D drawings in the design step. Accordingly, an efficient construction plan and direction is established according to budget. In such a case, construction is dependent on 2D drawings. At that time, a risk can occur easily. This study is aimed at reducing the cost and risk of interior construction by implementing 3D drawings with the use of the visual data of 2D drawings. For accurate analysis, 2D drawings were completed, and then 3D interior construction modeling for various buildings was conducted with the 3D modeling software 3D Max. According to the 3D modeling, it reduced the cost and risk more than 2D drawings based design, and influenced the improvement in the understanding of orderers and workers.

The purposes of this study was to investigate accuracy and indigenity of landscape plant species in planting design and construction at housing complex and offer basic data for improving precision of planting construction. The scientific name of landscape plant species was described in planting drawings at only two sites among twelve survey sites. According to analysis on indigenity of plant species in planting drawings, it was found that the component ratio of foreign species was the highest and the component ratio of native species at public housing complex was the lowest. The component ratio of landscape plant species in planting construction was severely differed to that of planting drawings. Also the component ratio of cultivar was higher than that of planting drawings due to planting of sevveral cultivars for one species in planting drawings. In the result of accuracy analysis on landscape plant species in planting construction, it was found that mean ratio of inacccurate species was 33.2% at public housing complex, 29.6% at local company housing complex and 26.4% at nationwide company housing complex. It was found that several cultivars were planted for one species in planting drawings. The representative species which were planted by several cultivars were Camellia japonica, Rododendron spp., Prunus spp. and Magnolia spp. and so on. In order to promote the precision and speciality of planting design and construction, scientific and cultivar name of plants should be described in planting drawings.

최근들어 공간정보의 최신성에 대한 요구가 늘어나고 있지만 현재 우리나라의 지도수정체계로는 국토정보 변화에 대한 대응이 곤란하여 이를 보완할 수 있는 방안의 모색이 필요하다. 이에 본 연구에서는 제도화된 내용을 토대로 준공도면을 활용하여 1/5,000 수치지도의 수정을 위한 방안을 마련하였다. 이를 위해 기존에 작성된 준공도면과 수치지도를 비교 검토하고, 다양한 국내외 사례와 각종 규정을 검토하였다. 또, 준공도면의 유형별로 대상지역을 선정하고, 준공도면을 활용하여 수치지도를 수정하였다. 다음으로 준공도면과 관련된 각종 제도 및 규정에 대한 검토 후 개선방안과 준공도면 활용방안을 마련하여 그 결과를 제시하였다. 본 연구의 결과와 지속적인 노력을 통해 신속하고, 정확한 지리정보를 제공할 수 있는 기반을 마련할 수 있을 것으로 기대한다.

현재 실시설계도면 작성과정에서 시간, 비용 등 제한조건으로 인해 실시설계도면 자체의 품질저하가 발생하고 있으며, 시공상세도는 표준화된 기준이 없이 임의적으로 작성되고 프로젝트 완료 후 대부분이 폐기가 되어 설계단계로 피드백 되지 않아 실시설계도면 품질저하의 악순환이 초래되고 있다. 본 연구에서는 실시설계도면과 시공상세도의 품질 향상을 위하여 일반업무시설에 대한 기존 실시설계 체크리스트를 기본으로 공사현장에 요구되는 정보와 시공상세도를 반영하고, 설계자의 설계도면 구성 분류에 따른 검토항목과 시공자의 공사별 분류 방법에 따른 검토항목을 상호 연계함으로써 시공성을 반영한 실시설계도면 체크리스트 개선안을 제시하였다. 실시설계도면과 시공단계가 연계된 공사별 통합 체크리스트의 활용성을 위해 인덱스 매트릭스를 개발하였으며, 실무전문가를 대상으로 심층면담조사를 통해 유효성을 확인하였다.

In shipbuilding, 2D manufacturing drawings are crucial for building a ship. Even various types of 3D models are being utilized for supporting ship manufacturing, which does not reduce the importance of 2D drawings. Recently things are changing in the shipbuilding industry. To reduce the number of 2D drawings or to reduce the quantity of information contained in 2D drawings, some attempts that can substitute for 2D drawings are being made. One of the attempts is to visualize lightweight 3D manufacturing models in a mobile device. In this paper, a method for displaying lightweight 3D models of a ship in an Android based device is introduced. To overcome the problem with parsing JT files in Android system, JT files are parsed in a Windows based server and as-simple-as-possible visualization data are transmitted to an Android based viewer. A comparison result with a commercial system is also given.

This paper explains the qualitative shape representation scheme and general shape analysis procedure based on shape feature categories. It takes two different groups of architectural drawings as examples and comparer them so as to confirm that the procedure is capable of comparing one group with another. In order to verify the validity of qualitative shape representation scheme, we used statistical methods as well as symbolic representation and analysis techniques. This paper concludes that two different groups of architectural drawings of similar kind are analyzed to be distinguished and specifically characterized. 11 drawings of Kahn and 13 drawings of Aalto are taken into considerations. Linear regressions are used in characterizing the shape featural relationships.

This paper presents a method that automatically recognizes dimension sets from the mechanical drawings, and that classifies 6 types dimension sets according to functional purpose. In the proposed method, the object and closed-loop symbols are separated from the character-free drawings. Then object lines and interpretation lines are vectorized. And, after recognizing dimension sets(consistings of arrowhead, shape line, tail lines, extension lines, text-string, and feature control frame), we classify recognized dimension sets as horizontal, vertical, angular, diametral, radial, and leader dimension sets. Finally the proposed method converts classified dimension sets into AutoCAD data by using AutoLisp language. By using the methods of geometric modeling, the proposed method readily recognized and classifies dimension sets from complex drawings. Experimetnal results are presented, which are obtained by applying the proposed method to drawings drawn in compliance with the KS drafting standard.
