| Abstract |
CAD layering is one of the major technologies to enhance the efficiency and effectiveness of architectural drawings. However, the absence of a specialized standard and education regarding the layering system has been a barrier to its practical application. This study tries to identify the problem of layers arbitrarily used by untrained users and aims to propose the standard of naming and structuring of CAD layers for aluminium door and window drawings. To find out the level of standardization in CAD layering systems in the detail drawings of door and window companies, the study analysed 30 sample drawings from ten different companies. The research methods includes both of the quantitative and qualitative analyses on the total number of layers used in each drawing, the ratio of layers shared among those drawings and, the actual use of layers according to the design element and the principle of layer naming. Through these methods this paper indicates that the standardization of practical usage of CAD layers in door and window drawings has hardly been accomplished in the industrial dimension and there was no evidence that even individual companies retained their own CAD layer standards. Based on this analysis with the consideration of KIA Standard Version 1.1, this paper will suggest a standard model of CAD layering system in aluminum door and window drawings. The adequate training and application of the standard is required to extend the industrial productivity in door and window drawings. |
